The thermal rolls of print media of this invention comprise a core/spindle and a sheet, preferably continuous, of a print medium of substantially the same width as the core/spindle. The sheet of print medium is wound around the core/spindle to provide a thickness of layered paper on the core/spindle of at least one half inch, measured from the periphery of the core/spindle to the outer layer of the sheet of print medium on the roll. At least one side of the wound sheet of print medium is marked with at least one impression which serves as an identifying mark. The "sides" of the roll of a print medium, as referred to herein, are where the edges of the wound print medium are exposed. The term "impression" as used herein includes shallow indentations as well as realignment of the edges of the wound print medium and realignment of the fibers within the wound print medium. In realigning the edges and/or fibers of the wound print medium, there may be no indentation which is detectable and in certain embodiments, no indentation at all.
Thermal paper rolls in the past is no longer true. While thermal tape used to be an uncommon alternative due to a short lifespan and high prices, it's now the most viable choice. Recent developments have led to better technology, including advanced chemical films and more durable substrata.
The rolling force and roll deformation behavior in the twin-roll-type strip continuous casting process have been computed to estimate the thermal characteristics of a caster roll. To calculate the rolling force, the relationship between the flow stress and strain for a roll material and a casting alloy are assumed as a function of the strain rate and temperature, because the mechanical properties of casting materials depend on temperature. Temperature field data for a caster roll, provided by the authors, were used to estimate the roll deformation. Therfore, numerical models considering the thermal and rolling forces have been developed to estimate the roll life. Roll life considering the thermal cycle is calculated using thermal elastic-plastic analysis results. The roll life is proposed in terms of roll revolution in the caster roll models with and without the fine crack failure on the roll surface. To obtain plastic strain distributions of the caster roll, thermomechanical properties of a roll sleeve with a copper alloy are obtained by a uniaxial tensile test for variation of temperature. The proposed analysis techniques have improved in caster roll design.

Take Care Of You Laptop Battery Or Else...
Laptops are common now; most people have them to take to school or when they travel for work. They're useful and easy to move with. What is also common is to see someone scrambling to find a place to charge a laptop battery. That report due tomorrow may suddenly be lost if you don't find an outlet within thirty seconds... Or that slideshow you have created (but carelessly forgot to save) may disappear if your laptop battery is not recharged.
As common as laptops are now, it is just as common to see individuals forgetting that the machine needs a little bit of help to run. It does not magically power itself; the battery does not somehow manage to stay full as you work for hours at a time. Yet, many seem to think that their battery does just that. No matter how long they stay hunched over the machine, it will work.
A few times of having the laptop die will cure that fantasy.
The truth is: you must keep your laptop charged. Yes, one of the advantages of having a laptop is that you can take it anywhere; it does not require you to remain plugged into the wall. That still does not mean that you can expect the laptop to run with a low battery. Yes, you can walk around with it; yes, you can wander away from your plug. You still should return, however, when your computer tells you it's low.
And they do tell you. Laptops feature a symbol at the top of the screen that allows you to see just how much your battery is charged. The lower it drops, the less time you have. This is basic. Anyone will even a small trace of knowledge should know and understand this. Yet, too many people risk losing everything to squeeze out an extra minute on their battery. These are the same people who try to frantically finish a report as opposed to saving and heading to their charger, only to lose the majority of it when the computer quits. And these are the same people who swear they will never do it again, but forget that promise the next time around.
Laptop batteries have short ives. They can fail as quickly as thirty minutes. Some last longer, of course, but the result is still the same: if you are not careful and don't pay attention, the battery will die. Of course, laptops offer warnings when a battery is low. Often, a small screen will pop up to remind you that the time is almost there. Still, thinking you can simply ignore that screen since you're busy is not the wisest of moves.
This are basic ideas, and you may be rolling your eyes, wondering who would be so foolish. But it does happen, all-too-often it happens. Because of this, you must make an effort to remember that, as convenient as your laptop is, it is still a machine and therefore needs care. Check your laptop battery and keep it charged.

Blu-Ray set to take the world by storm!
The Blu-ray Disc belongs to a new generation of optical discs capable of staging high density data. Blu-Ray technology is based on a blue-violet coloured laser. The blue laser operates at a wave length of 405 nm, while older technology such as DVDs and CDs are based on red and infrared lasers that works at 650 and 780 nm. Since the wave length is shorter with a blue laser, the new Blu-ray technology makes is possible to store much more information
The advantage with the Blu-ray technology is that the laser beam can be focused much more tightly at the surface of the disc. Tight focus means that a smaller spot will be produced on the surface on the disc, and when the spots become smaller there will naturally be room for more information on each disc. The minimum spot size of any laser depends on a naturally accruing phenomenon called diffraction. The narrow beam of light sent out from a laser will always diverge into a wider beam eventually, due to the natural diffraction of waves. Diffraction will also occur the waves meet an obstruction. By reducing the wavelength of a laser, we can affect the diffraction.
In Blu-ray technology, the diffractions is also affected by the fact that the lens used to focus the light has a higher numerical aperture than the lenses found in ordinary DVDs - 0.85 instead of 0.6. Blu-ray technology based appliances are also equipped with a dual-lens system of supreme quality, and the cover layer has been made thinner in order to prevent unwanted optical effects. All this makes it possible for a Blu-ray laser to focus on much smaller spots. The optical improvements are accompanied with a new method for encoding data which makes it possible to store even more data on the Blu-ray disc.
The standard for Blu-ray technology has been developed as a joint venture between several major manufacturers of PCs and consumer electronics, including Sony and Philips. The group is called the Blu-ray Disc Association (BDA). The first Blu-ray recorder was launched in Japan in 2003, by Sony. Today, Samsung, JVC, Matsushita (Panasonic) and LG Electronics are all examples of companies using Blu-ray technology in their products. Hewlett Packard has announced that they will release desktop PCs equipped with Blu-ray technology in late 2005.
The main competitor for the Blu-ray technology is the HD DVD format which is also capable of storing more information than a normal DVD. The Blu-ray technology does however allow for more information per layer than the HD DVD format – 25 GB compared to 15 GB. The Blu-ray technology will on the other hand most likely be more expensive to support, at least initially, which can make the HD DVD a tempting alternative. In a Blu-ray disc, the data is stored extremely close to the surface. This made the first Blu-ray discs extremely vulnerable to scratching and many users preferred the tougher HD DVD discs. Since 2004, all Blu-ray discs are coated with a clear polymer called “Durabis” which makes them much more durable. According to the developers of Durabis, the TDK Corporation, a coated Blu-ray disc will work even after being attacked with a screwdriver.

Wireless Lan And Laptop Computers
A small business run from home or on rented space, while it can be extremely profitable, cannot be furnished in the same style as a large-scale company office. Using standard full-size desktop computers in such a set up is impracticable, as it takes up too much space and is too bulky for cramped confines. To deal with such a situation, desknotes or transportables may just hold the key.
Desknotes are systems that can be alternately used as a standard desktop PC, but also offers portability into the bargain. Desknotes have the same power levels as a desktop PC and occupy much less room. Moreover, to keep expenses to a minimum, it is possible to install a LAN amongst the desknotes, where only one laptop need be connected to the Internet and access is shared to all the laptops connected to the network. This is also true for the devices connected to the central laptop; through LAN, all the laptops can use the same device. Thus, for small offices with three or more laptops, LAN (Local Area Network) is surely a boon.
LANs usually span a building or a small group of buildings. Connecting one LAN with many others through telephone lines and radio waves is called WAN (Wide Area Network). A Local Area Network that uses radio waves to communicate is called WLAN (Wireless Land Area Network). There are several advantages to WLANs. One is its flexibility. Radio waves can pass through walls of nearly any surface, and also do not require miles and miles of cables, thus offering a clutter-free work atmosphere. Wireless LAN can be almost invisible!
Another advantage is that WLANs are extremely easy to use. Most laptops are built in with WLAN capability. So all you need to do is plug in and make sure you have a wireless LAN card. WLANs are very tough. If one base becomes disconnected, it is possible to use another laptop as a base and can be shifted physically into the range of another WLAN. Prices are very low these days for WLAN, and it is no wonder the choice for home networks.
However, as nothing is perfect in this world, WLAN does carry a few disadvantages. Anyone can operate a laptop near a WLAN and hack into the stored wireless traffic. This makes safety an issue due to the loss of privacy. While radio waves can pass through almost any surface, too many obstacles in the path such as buildings can degrade the transmission. Another drawback is the data transfer speed. As many laptops share the same bandwidth, data transfer speeds are significantly lower in a WLAN. In addition to this, wireless data rates fall according to signal strength or interference.
Wireless LAN is convenient where mobility is required, and is the only choice in old buildings where cables cannot be installed. Companies usually provide wired connections for fixed offices, and wireless LAN for those users who have no fixed location. In the end, WLAN should be installed only after taking into account all factors regarding your office or home set up.

Tips for Perfect Prints (For Beginners)
Undeniably, photo prints still remain the most popular way of sharing memories. With the right printer and a handful of simple techniques, your pictures can look as sharp as the lab-processed ones. Read on for some great tips for getting the best prints possible.
Start with a Good Image
The first thing you need to get a good print — a high-quality image. An image that merely looks good onscreen is not enough. Here’s what a good image file would have:
Good Resolution
Resolution refers to the number of pixels in an image {usually stated in dpi (dots per inch) or PPI (pixels per inch).}. The more pixels a photo has, the more clarity and detail it will retain as you increase its dimensions. Resolution can also be expressed by the width and height of the image, and the total number of pixels it contains. For example, an image that is 1500 pixels wide and 2100 pixels high (1500 x 2100) contains 3,150,000 pixels—or almost 3.2 mega pixels.
Most digital cameras offer a variety of resolution settings. It’s a good idea to use a higher-quality setting if you plan on printing large sized pictures. Here are some general guidelines:
Less than 640 x 480 pixels = Wallet-size prints. Good for E-mailing to friends , picture displays on the refrigerator etc.
640 x 480 pixels = 4" x 6" photo prints. These are going to be best for photo albums, General usage including craft projects (scrapbooks, stickers, etc).
1152 x 864 pixels = 5" x 7" photo prints. These are good for framing for home display, screensavers and photo greeting cards
1600 x 1200 pixels = 8" x 10" or larger. Good for framing, screensavers for home or gallery display and photo calendars
Best Format
Even if your image is high resolution, you will still need to save it in the correct file format: TIFF or JPEG. For best printing results, always save your pictures in the TIFF format (example: my_friends.tiff). Although this format results in a slightly larger file size, it will produce the most satisfactory results. The JPEG format (example: my_friends.jpg) is preferable for e-mailing photos as it results in smaller, compressed files—ideal for sending electronically.
Quality Control
Use a good image-editing program to remove dust marks and specks on your photos. The printer will most definitely pick up imperfections even if they're very small. You can also use the sharpening option to more clearly define the edges of objects in your print.
Use a Good Printer and Know How to Use it
Once you are familiar with the features and settings of your printer, you will be able to get the best possible results.
Avoid DPI Dilemmas
Dots per inch (dpi) is a measurement of print resolution that indicates the number of individual dots a device can create on a page per square inch of area. For crisp, colourful, professional-looking prints, you should choose a printer with at least 600 x 600 dpi. Otherwise, your photos may turn out pixilated (objects will appear jagged and speckled).
Printer Drivers
Printer drivers play the role of translators, acting as a medium of communication between your printer and computer. To help fix problems and bring significant performance improvements, it is important to use the most current version available for your printer. Printer manufacturers regularly update drivers, and you can download new versions for free from the company’s website.
Resolution Settings
Refer to your printer’s manual to learn how to change quality settings. Usually, you would want ‘best quality’ resolution for photos; however, for wallet-size prints, ‘normal’ resolution may be enough. Experiment with your printer settings to see which ones give you satisfactory results.
Paper Settings
Paper settings control the amount of ink that is laid down on paper; therefore, using the setting that matches your photo paper is essential to making good prints. When you find a setting that works best for a particular paper type, make note of it so you will be able to get the same results when you use that paper again.
Clean and Clear
Running the ‘clean’ function in your printer every two to three months improves print appearance and prevents problems such as streaking and clogging. You can access ‘properties’ settings to perform maintenance actions such as cleaning the printer nozzles and aligning the print head.
Understand Your Ink and Paper
Your choice of printing supplies, such as paper and ink, can make the difference between a good print and a great one.
Paper and Ink Selection
Using Original Equipment Manufacturer (OEM) supplies would definitely assure you of the quality but they come with a price. Nowadays, Canon and HP boast of inks that deliver optimum colour and fade resistance up to 110 years. Non-OEM supplies are definitely cheaper, but its debatable whether they can achieve the same quality.
Drying Time
Before you frame a photo print or add it to a scrapbook, be sure to give it enough time to dry. Most OEM inks and papers are designed to dry within an hour or so, but it is best to allow the print to dry for about 24 hours prior to framing or placing it in a photo album.
If you are printing multiple pictures, remove them from the printer slide as they come out and set them aside. This will eliminate any chances of accidental smearing or running.

The Necessity of Barcode Printers in Modern Times
A barcode is a machine-readable representation of information in a visual format on a surface. Barcode is widely used to implement Auto ID Data Capture (AIDC) systems that improve the speed and accuracy of computer data entry.
A barcode printer is a computer peripheral for printing barcode labels or tags that can be attached to physical objects. Barcode printers are commonly used to label cartons before shipment, or to label retail items with Universal Product Codes.
Desktop barcode printer has become a commonplace tool for entering product information at retail chains and shopping complexes. Industrial barcode printers are used in manufacturing facilities and large warehouses helping in inventory management and sales process automation.
The most common barcode standards are UPCs and EANs.
Universal Product Code Bar Code - The standard bar code printed on retail merchandise. It contains the vendor's identification number and the product number which is read by passing the bar code over a scanner.
European Article Numbering is the European standard for barcodes. There are two different versions of EAN bar codes, EAN-13 and EAN-8, which encode 13- and 8-digit numbers, respectively. A special EAN-13 bar code with a 5-digit supplemental code is used on books to encode the International Standard Book Number (ISBN) and the price. This bar code is called “Bookland”.
Traditional one-dimensional bar codes use the bar's width to encode a product or an account number. Two-dimensional bar codes, such as PDF417, MaxiCode and DataMatrix, are scanned horizontally and vertically and hold considerably more data. PDF417 is widely used for general purposes. MaxiCode is used for high-speed sorting, and DataMatrix is used for marking small parts.
Barcode Printers employ two major printing methods – Direct Thermal (DT) and Thermal Transfer (TT).
Direct thermal printers use a print head to generate heat that causes a chemical reaction in specially designed paper that turns the paper black. Direct thermal printers are generally less expensive, but they produce labels that can become illegible if exposed to heat, direct sunlight, or chemical vapors. Barcode printers require regular cleaning of the ribbon and the print head. Specks of dust may cause distortion of the bar codes. The outputs of these printers using ANSI software need to be continuously checked in order to check for system malfunctions.
Thermal transfer printers also use heat, but instead of acting directly on the paper, the heat melts a waxy or resin substance on a ribbon that runs over the label or tag material. The heat transfers ink from the ribbon to the paper. Thermal Transfer requires the use of a heated ribbon to produce long-lasting images of data onto a label and/or tag, whereas Direct Thermal process prints the image directly on the label/tag.
Direct thermal and thermal transfer barcode printers can print bar code labels on variety of media. The range of bar code printers vary from light duty printers to rugged and high speed industrial printers for meeting diverse requirements. In industrial printers, the range varies from medium to heavy duty to extra heavy duty printers. These printers can be integrated to existing applications / ERP for on demand label/tag printing.
Industrial barcode printers are used in large warehouses and manufacturing facilities. They have large paper capacities, operate faster and have a longer service life. For retail and office environments, desktop barcode printers are most common.

Simple Steps to Buying a Laptop
It’s easy to be confused by all the different options when purchasing a laptop computer. There are literally hundreds of models to choose from for all different prices.
The key to finding the right laptop for you is determining firstly what your needs are going to be, then determining how much money you are willing to spend.
There are some general factors to consider. The first would be the size of the laptop. Do you want an ultra portable laptop that’s small and light weight or do you want something more like a desktop replacement while compromising on size and weight.
The second factor to consider would be the size of the hard drive on the laptop. Laptop hard drives are a lot smaller than desktop hard drives. A standard laptop hard drive size would be around 100gb. If you need to store large files such as videos then you would have to consider getting something with an upgraded hard drive.
The third factor would be the size of the memory. A standard size would be 256-512mb. Anything above this would cost extra. You would need to consider what you are going to use the laptop for. If word processing and web surfing is all you want to do then 256mb would be more than enough.
The final factor would be pricing. This is completely a personal choice but you do get what you pay for. Laptop prices have dropped dramatically these days and a laptop can be bought for as little as $1000. Considering a couple of years back you couldn’t get a laptop for under $2000 this price isn’t too bad. But of course it all comes back to your needs. If a high end laptop is what you need for picture or video editing then expect to be paying over $2500.
Buying a laptop doesn’t need to be a difficult task. If you evaluate your needs first and choose carefully your new purchase will be a profitable one.
The key to finding the right laptop for you is determining firstly what your needs are going to be, then determining how much money you are willing to spend.

Protect Your Data with an External Backup Drive
Computers are a very important part of our society, both in a business environment and personally. Having a home computer has been very common for both fun and work purposes. It is common to have pictures saved on your computer as well as some of your financial information. Losing data due to a virus or computer crash can be devastating. The process of recovering all that information is very time consuming and expensive.
In many such instances the data is simply lost forever. If you have important information that you don’t want to be without you need to protect yourself now. Too many people wait to invest in an external backup drive until after they have experienced such a loss. You will find them readily available for desktop and laptop computers.
With an external backup drive, the data isn’t physically stored on your computer system. You will use a type of zip disk to store the information on. Make sure you label the disks accordingly so that you know what is on each one of them. Should you not be able to retrieve the original information that is on your computer you will be able to pull out these disks and continue using your data.
The cost of the hardware for an external backup drive depends on what brand you purchase. It also depends on the amount of storage space you need it to have. Generally you want it to have as much storage space or more than your computer does.
However, the investment is generally very minimal and you will find it to be well worth it. Just one problem with your computer will cost you more than a backup drive for data retrieval and the time to try to piece together or redo the information that you have lost.
It is a good idea to invest in good quality disks for the external backup drive as well. You don’t want to purchase cheap disks and then realize that the information can’t be retrieved from them either due to poor manufacturing.
Take your time to find an external backup drive that is affordable, offers plenty of storage space, and is easy to install and use. In most instances you can install the external back up drive in less than an hour. This includes downloading and installing the necessary software for it to operate. Once it is in place you can just make a few clicks to save information to the disks as a back up resource.
Being able to rely on your computer for a variety of tasks is what makes them such an important part of our society. Be prepared for the unexpected though and always use an external backup drive to protect your data. This is a much easier process than having the nightmare of trying to piece back what data you can retrieve and having to do without the rest of it. You never know when your computer will experience a problem or be the target of a virus. Don’t let these issues cause you time, money, or frustration.

Numerical models considering thermal roll and rolling forces.
The thermal rolls of print media of this invention comprise a core/spindle and a sheet, preferably continuous, of a print medium of substantially the same width as the core/spindle. The sheet of print medium is wound around the core/spindle to provide a thickness of layered paper on the core/spindle of at least one half inch, measured from the periphery of the core/spindle to the outer layer of the sheet of print medium on the roll. At least one side of the wound sheet of print medium is marked with at least one impression which serves as an identifying mark. The "sides" of the roll of a print medium, as referred to herein, are where the edges of the wound print medium are exposed. The term "impression" as used herein includes shallow indentations as well as realignment of the edges of the wound print medium and realignment of the fibers within the wound print medium. In realigning the edges and/or fibers of the wound print medium, there may be no indentation which is detectable and in certain embodiments, no indentation at all.
Thermal paper rolls in the past is no longer true. While thermal tape used to be an uncommon alternative due to a short lifespan and high prices, it's now the most viable choice. Recent developments have led to better technology, including advanced chemical films and more durable substrata.
The rolling force and roll deformation behavior in the twin-roll-type strip continuous casting process have been computed to estimate the thermal characteristics of a caster roll. To calculate the rolling force, the relationship between the flow stress and strain for a roll material and a casting alloy are assumed as a function of the strain rate and temperature, because the mechanical properties of casting materials depend on temperature. Temperature field data for a caster roll, provided by the authors, were used to estimate the roll deformation. Therfore, numerical models considering the thermal and rolling forces have been developed to estimate the roll life. Roll life considering the thermal cycle is calculated using thermal elastic-plastic analysis results. The roll life is proposed in terms of roll revolution in the caster roll models with and without the fine crack failure on the roll surface. To obtain plastic strain distributions of the caster roll, thermomechanical properties of a roll sleeve with a copper alloy are obtained by a uniaxial tensile test for variation of temperature. The proposed analysis techniques have improved in caster roll design.

Laptop Batteries and Laptop Battery Care
Laptop Batteries are essential for keeping a laptop running properly. In many cases, businesses, whether personal or corporate, depend on laptops for business dealings day to day. There are a number of ways to properly care and maintain a laptops main power source, the battery. Battery construction of laptop batteries is very different from other traditional electronic device batteries. A brief overview of the construction of laptop batteries will help provide insight into factors that affect the life and care of laptop batteries.
Laptop batteries are constructed with a number of crucial components to regulate charge and power supply to the laptop. A thermistor measures the charge of the battery and regulates how much charge the laptop sends to the battery. When the battery is fully charged, the thermistor tells the laptop to stop charging. Safety fuses and breakers in the laptop battery also help prevent overcharging and aid in overall functionality of the laptop battery. So there is an essential communication that must occur between the components of the laptop battery and the laptop itself to ensure proper function of both the computer and the power supply.
Laptop batteries are becoming more advanced that other types of batteries. In the past they were constructed of NiCd or NiMH which provided less power and did not recharge well. Lithium polymer batteries are the newest revelation in battery technology and they are leaps and bounds beyond old metal batteries. They provide the right amount of power and charge in a fraction of the time of metal batteries. The advantages of lithium batteries make new laptop batteries more practical. Lithium batteries therefore help improve the life of laptop batteries and also make them a more valuable battery for the money.
There are a number of precautions to take to ensure safe and practical function of the laptop battery. Some laptop batteries can become overheated from charging which can create a fire hazard. It is important to place the laptop battery in a location that is free of flammable objects such as paper or furnishings. In general, it is good to avoid extreme temperatures for proper optimal function of a laptop battery. Battery life of a laptop battery depends greatly on how the laptop is used. A laptop battery will not last very long without being charged. A useful method to extend battery life is to close as many unnecessary programs as possible. By closing programs that will not be needed will save useful battery life.
These are just a few pieces of information about laptop batteries that will help the user understand how to care for laptop batteries and how to manage laptop battery life. There is much more information about laptop batteries, including battery construction, battery charging and much more.

Flash Card: When Size Really Matters
Few years back, we never really imagined how memory storage would evolve into flash cards we know today. It is ever harder to believe that the tiny rectangular piece of plastic could store thousands of pictures, hundreds of songs, and even movies. Remember few years ago when storing files could mean we have to settle for 3.5” and the outrageously large 5.25”? You know what I mean right? Those we have thought the future of memory storage- the floppy disks? With the amazing capacity to store as much as 1.44 MB of files, these floppy disks are really works of technology.
But as we all know technology would not stop to evolve. This is the reason why floppy disks are now the thing of the past. And as the years go by, we have received memory storage cards that are as size of post stamps. We even amaze old folks when we remove in from of them those tiny card out from digital cameras, cellular phones, and computers.
One of the earlier flash cards have the memory capacity not far from floppy drives. 2 MB is enough considering you have the reference point of 1.44MB. Shortly, the 4 MB came out. From then on, several more powerful, smaller, and larger storage flash cards came out. The 8, 16, 32, 64, and 128 MB came out. Up to now, the 128 MB flash cards are still being used although much higher memory cards are now in the market.
Today, several digital devices are using 1 GB, 2 GB, 4 GB, and even 8 GB and 16 GB flash cards. Those are the capacity of hard drives just year ago. While hard drives are as size of car stereo cut in half, flash cards can fit to your pocket just like having a penny. The benefits of flash cards could be seen more popularly on digital cameras where they can sit peacefully to the camera’s size. How about computers? Computers still use hard drives to store memory. And if you want some portable drives, the flash memory sticks are used. Like flash cards, they are small with large amount of memory capacity.
You might wonder how can a single tiny card hold such large files. Let us put it this way: your file cabinet could only store limited amount of files. And large cabinets are big. Big if you are going to store all these filed digitally, meaning using electronic codes, you can store as much files in one tiny storage just like the flash card. Another reason is that flash cards have removed unnecessary components that could enlarge the size of the card.
There are several types of flash cards used today particulry on digital cameras. These came in different sizes depending on the device it is designed to fit in. Here are several types of flash cards used: MultiMediaCard (MMC), Memory Stick (MS), CompactFlash (CF), Secure Digital (SD), SmartMedia (SM) and xD-Picture Card (xD).
The sizes also depend on the capacity of the flash card against one another. But the bottom line is, flash cards, no matter what the size is, still carry significantly large amount of files in one tiny square-shaped plastic card. Who knows, in the future we might se 80 GB flash drives that can record and store several hours of video.

Computer lessons for beginners : how to use a computer mouse
Learn how to hold the computer mouse:
Hold the sides of the mouse with your thumb on one side and ring finger or pinkie, which ever feels more comfortable to you, on the other side. Your index finger goes on the left button and your middle finger on the right button. (Some computer mice only have one button, some have several, some have a wheel which you can use your middle finger to depress the wheel then turn it up or down to scroll pages very quickly or slow depending on how quickly you turn the wheel. Personally I love the wheel and would not have a mouse without it!) When you are told to 'click' use the button under your index finger, or the left button.
Learn how to move the computer mouse:
Slowly slide the mouse around on the mouse pad. See what happens to the arrow on the screen as you slide it around.
Do you need a mouse pad:
You should have a mouse pad under your mouse, (although the new optic mice do not require one). You will have an array of choices when purchasing a mouse pad; find the one that is comfortable for you. Rest your hand on the mouse pad or desk and move it slowly, there is no need to lift the mouse off the mouse pad unless you run out of room, then you just lift it up and reposition where needed. You don't need to move the mouse to the left or right, simply slide it left or right with the buttons still facing away from you.
What does clicking do:
Clicking sends a command to the computer. To click, gently press and release the left computer mouse button. Be careful not to move the mouse while you are clicking, if you accidentally do simply slide the mouse back to where you want to click and try again. Try to keep you hand relaxed on the mouse as you press and release without lifting your finger completely off the button.
You are Done - Great job! That is all you need to know to start using your computer and that mouse. Keep working on it and before you know it, it will feel like second nature to you and you will not even have to think about what you are doing.

Checking To See If You Have Wireless Capability
Do you know if your new computer already has wireless capability? Many new computers have the built-in software and connections in order for you to set up a wireless network. These wireless networking devices are so inexpensive that the manufacturers of the computers include them as part of the package and can be found on the system specification list.
Like most people, however, you may not even know how much memory your computer has, let alone whether it arrived already wireless-enabled. This is especially true if you don't know what wireless networking is. It's easy to ignore this detail in the specifications that come with the computer and to fail to take the time to set it up and get it working. Let’s look at some things to look for if you want to check your computer's wireless capabilities.
Intel Centrino
If you own a laptop that comes with something called 'Intel Centrino mobile technology', this is what you’re looking for! Unfortunately, manufacturers of computers are not good at explaining what this technology is or does. Quite simply, it means that your laptop has wireless networking built right in; you don’t need to do a thing! Intel Centrino is a term used in marketing that stands for a combination of the Intel Pentium M processor and Intel's Pro/Wireless card.
Your computer should have an 'Intel Centrino' sticker on it somewhere if it is enabled with Intel Centrino. If you don’t see this type of sticker, you can also check the name of your processor by right-clicking the My Computer icon in the Start Menu (or on your desktop) and clicking on “Properties” from the menu. Look at the wording following the word “Computer” in this section. It should tell you if it has the wireless feature.
Intel Centrino technology has the capability of increasing the life of your computer’s battery and allows computers to be smaller in size. If you didn't buy an Intel Centrino laptop but your laptop has a free card slot, adding wireless capabilities will be no problem.
Desktop Computers
Desktop computers come with wireless capabilities, too. If you're not sure whether or not your desktop computer has a wireless connection, turn it around and look at the back of the computer. If a wireless connection is present, you can generally see a small aerial antenna sticking out of the back of the computer near the bottom of the computer.
If you don’t see anything there, it's still possible that you have a wireless device in the computer, especially if the computer is relatively new. Unless you’re a computer expert, don’t open the back of your computer to determine if it has wireless capabilities. Instead, you should probably try and figure it out using Windows.
Checking in Windows
You can easily check your computer’s wireless capabilities by going into Windows' Device Manager. You must first right-click My Computer and choose Manage from that menu. Now click on “Device Manager”.
In device manager, you will be able to see a list of the different devices you have or would be able to have on your computer. Look under 'Network Adapters'. Anything that uses the words '10/100' or 'Ethernet' is a normal network connection and isn’t related to wireless connectivity. Anything else may be a wireless device.
If you think you have a wireless device but note that it has a yellow warning sign next to its name in the Device Manager, click its name to find out what is wrong with the device. Windows should be able to let you know why the device is not working. The computer may also suggest that you go into its troubleshooter program. Try doing that before trying anything else.
The problem could be a driver problem. In that case, insert the drivers CD that came with your computer. If you can’t find the drivers CD, you can always find the drivers online. In order to do this, you should look on the website of the computer's manufacturer. From there, you can try searching for the particular name of the wireless device in Device Manager.
Unfortunately, it could turn out that you don't have a wireless device after all. That’s too bad. On the bright side, it is much better to learn that now than it would be to buy wireless equipment and then realize you couldn’t run it on your computer. In any event, even if you did find a wireless device in one of your computers, you may decide that you need even more wireless capability. Fortunately, wireless technology is getting cheaper all the time!
Like most people, however, you may not even know how much memory your computer has, let alone whether it arrived already wireless-enabled. This is especially true if you don't know what wireless networking is. It's easy to ignore this detail in the specifications that come with the computer and to fail to take the time to set it up and get it working. Let’s look at some things to look for if you want to check your computer's wireless capabilities.
Intel Centrino
If you own a laptop that comes with something called 'Intel Centrino mobile technology', this is what you’re looking for! Unfortunately, manufacturers of computers are not good at explaining what this technology is or does. Quite simply, it means that your laptop has wireless networking built right in; you don’t need to do a thing! Intel Centrino is a term used in marketing that stands for a combination of the Intel Pentium M processor and Intel's Pro/Wireless card.
Your computer should have an 'Intel Centrino' sticker on it somewhere if it is enabled with Intel Centrino. If you don’t see this type of sticker, you can also check the name of your processor by right-clicking the My Computer icon in the Start Menu (or on your desktop) and clicking on “Properties” from the menu. Look at the wording following the word “Computer” in this section. It should tell you if it has the wireless feature.
Intel Centrino technology has the capability of increasing the life of your computer’s battery and allows computers to be smaller in size. If you didn't buy an Intel Centrino laptop but your laptop has a free card slot, adding wireless capabilities will be no problem.
Desktop Computers
Desktop computers come with wireless capabilities, too. If you're not sure whether or not your desktop computer has a wireless connection, turn it around and look at the back of the computer. If a wireless connection is present, you can generally see a small aerial antenna sticking out of the back of the computer near the bottom of the computer.
If you don’t see anything there, it's still possible that you have a wireless device in the computer, especially if the computer is relatively new. Unless you’re a computer expert, don’t open the back of your computer to determine if it has wireless capabilities. Instead, you should probably try and figure it out using Windows.

Carbonless paper roll uses a chemical reaction between two different.
Carbonless paper uses a chemical reaction between two different contacting coatings to transfer an image when pressure is applied. A paper that is most often used for multiple part forms, it contains a chemical coating on the front side (designated as CF) or on the back side (designated as CB), or on both sides (designated as CFB). When a handwritten or machine impression occurs on the first sheet of multiple parts, the impression transfers from one page or ply to the next due to the bursting of tiny microcapsules in the chemical coating used to release a darkened copy of the impression occurring on the first sheet.
A method and apparatus are provided for producing a foam wrapped package for protecting a roll of pressure-sensitive carbonless copy paper. Interleaved foam and film are wrapped under tension around the outer periphery of the roll of carbonless paper by selectively rotating the roll and separately feeding packaging foam and stretch film toward the rotating roll.
The present invention relates to a process for producing a foam wrap package, and, more particularly, to a process for wrapping and protecting a roll of pressure-sensitive carbonless copy paper by simultaneously wrapping interleaved layers of stretch film and packaging foam onto the roll of carbonless paper.
Heretofore, stretch wrapping machinery manufacturers have marketed equipment which combines spiral wrapping of stretch film with limited non-spiral wrapping of a single face corrugated medium or a kraft wrap. Traditionally, machines have been developed which provide foam wrap in one operation and then kraft wrap in a second operation, and have required a substantial amount of the wrapping process to be performed by hand.
Problems have occurred in the prior art with the existing foam/kraft packages. Specifically, these packages using kraft wrap cannot apply foam over the edge of a roll of pressure-sensitive carbonless paper without producing a bulky edge that makes roll stacking difficult. The absence of foam over the edge of the roll of carbonless paper leaves the roll subject to edge damage. Prior to this time a sufficient wrapping procedure or a final wrapped package has not been achieved in the art which would require only a relatively limited capital cost and produce a resultant packaged product which is easy to handle.

Building A Computer Introduction
If you are reading this article, you are probably wondernig, why and how do you build a computer. Building your own computer is more simple than you think and has many benefits.
Why Build A Computer?
Building a computer has many benefits over buying a premade. First of all, it is generally cheaper if you build your own than buying one. If you shop your components, your DIY(Do it yourself) computer will be cheaper than its premade equivalent. If you build your own computer, it will be faster than one that is premade, because most computer manufacturers use cheap components and try to cut corners to cut down costs. Additionally, your self built computer has more room to upgrade if you so decide to in the future. Prebuilt computers usually only have enough expansion slots for the components that are going to be in the computer. Because of this, your prebuilt computer will become obsolete sooner. Also, building a computer is a satisfying experience and you will learn more about how your computer works.
How do I go About Building a Computer?
Building a computer is probably much simpler than you think. Especially now, things have been simplified and standardized. First, you pick out components and make sure they are all compatible. Once you get the parts, you put them together! This guide was made to show you how to do everything and contains pictures and good information to make building a computer a fun and rewarding experience.

About Laser Printers
Like with many other things in the world of printing, laser printers have come a long way in the past few years. They have gone from being found almost exclusively in offices to being offered at $100 for a home user. Although they are better for a lot of people, some have a hard time imagining themselves buying a laser printer for their home. A lot of people have the idea that laser printers are just the big clunky machines in their offices where the toner cartridges cost a fortune. However, if you are someone who prints out a large amount of documents and is tired of always having to buy new black inkjet cartridges, laser printers can be the solution. Once you get past the initial sticker shock of buying laser toner cartridges, you will realize the numbers for an entry level laser printer versus an inkjet printer look something like this:
Typical toner cartridge - $50-$60
Page yield - 2,000-3,000 pages
Average cost per page - 2-2.5 cents per page
Typical inkjet cartridge - $20-$30
Page yield - 400-500 pages
Average cost per page - 4-6 cents per page
Although these are just averages and may not seem all that different, in general if you are printing documents, it will probably cost you twice as much to run an inkjet printer than a laser printer. It is better to think of things in the long term when it comes to laser printers, because only then will you truly appreciate their value. If you buy a laser printer and then a backup toner cartridge at the same time, by the time you will have finished that second cartridge, you would have gone through roughly 10 inkjet cartridges.
So if you aren't into printing color, then you are probably better off going with a laser printer over a standard inkjet printer. You will appreciate the speed and low maintenance of a laser printer, while also saving money on printer ink in the long run.
Typical toner cartridge - $50-$60

What's A Pen Drive?
A Pen Drive is a removable storage device that plugs into a computer's USB port. Small enough to carry on a key ring, Pen Drives are great for transferring photos, music, documents and any other data from one computer to another. Different manufacturers over the years have named their Pen Drives with many different names causing constant confusion.
As a result of this the Pen Drive can also be known as Pocket Drive, Thumb Drive, Jump Drive, USB Flash Drive, USB Flash Memory Drive, USB Key Drive, USB Memory Key and USB Memory Stick among many others!
Although none of these names are either correct or incorrect, one of the names cause a huge amount of confusion for people, this is when someone referring to a Pen Drive, uses the term "Memory Stick". This is because "Memory Stick" is a Sony trademark and refers to a type of memory card used in Sony's electronic devices, it is therefore a completely different product, which will not plug directly into your computer's USB port!
Pen Drives were invented by IBM in 1988 as a replacement to Floppy Disks but were never patented by them, M-Systems who were later contracted in by IBM to manufacture Pen Drives actually own the patent. So think of a Pen Drive as a modern day floppy disk. The main difference being that a floppy disk contains moving parts which can make the data stored on it vulnerable, a Pen Drive is solid state meaning there are no moving parts inside, making it resilient to dust and everyday magnetic fields and so a safer storage option. Also Pen Drives can hold much, much more data than the floppy disk.
Once connected to a computer's USB port the Pen Drive appears in Windows as a "Removable Drive" alongside your C Drive, CD ROM Drive etc. You can simply drag and drop photos, music, documents and any other type of data on to the "Removable Drive" just as would with any other folder on your computer (no complex recording like CD or DVD is required). The Pen Drive can then be removed (see Safe Removal of Pen Drive below) from the computer and plugged into another computer's USB port giving you access to the information you copied to the Pen Drive.
The compact size, robust nature and low cost of the Pen Drive has made it a big hit and an indispensible tool for many. It is ideal for transporting personal, or work data from one location to another, i.e. from home to school or office, or for carrying around data that someone may want to access in a variety of places. An insurance company in the US loads customer bio data and policy details on a tiny Pen Drive and advises policy holders to wear it with a neck strap in case of emergencies, another company is doing the same with policy holders who go Sking. Another company videos their conference and records it onto the Pen Drive so that the delegates can refer to it in future. Pen Drives can also be used to back up your important documents.
If you would like to know more about Pen Drives please visit our website or call us on 0845 257 2088 (9am-5pm Mon-Fri) and we will do our best to assist you. Mouse2House.co.uk supply thousands of Pen Drives to Schools, Hospitals, Businesses, Government agencies and of course private individuals. We are also able to personalise Pen Drives with logos and messages for commercial or fund raising events, minimum order quantity applies to the logo service.

Toner Cartridges: Should you use Remanufactured or Compatibles?
First a little history....
In 1938, the first invention that would lead to the laser printer and toner cartridge was patented. The process, knows as "electro photography", used a dry printing method, not that different than today's laser printer. It was 1948, however, before the commercial application of electro photography because available.
In 1959, the first automatic reproduction machine, the Xerox 914, which used a dry printing process. In 1978, the fine tuned technology was applied to the computer printing needs of business and private citizens. Physically large and with a large price tag as well, the Xerox 9700 laser printer that used a toner cartridge wasn't affordable by individuals except the wealthy.
Everything changed in 1984 when Hewlett Packard began to market the "LaserJet" printer. This printer came with a replaceable toner cartridge that was not difficult to change, although it could sometimes bit a little messy. The really problematic part was that people who used the LaserJet had stacks of expensive but empty toners stacked in the storage room or wherever they could find to store the toner cartridges.
This problem was quickly resolved by environmentally aware designers by re-manufacturing the laser toner cartridge. This significantly reduced the cost of using laser printers.
What’s happening today?....
Nowadays we have the luxury of having a laser printer on our desk at home if we want that type of printing. The as well as the initial outlay for the printer has become quite affordable and provides a unique, very professional looking print out.
Today, laser printers are manufactured by many companies and the price tag is only slightly more than the common ink printer (though colour laser printers are still quite expensive the gap is getting smaller). The laser toner cartridge costs have been reduced so that it is reasonable to use the laser printer at home as well as at the office. In fact the toners are usually much cheaper when you take into account the larger number of pages you get for the amount you pay (the industry uses the terminology ‘cents per page’ or CPP)
Basically there are 2 types of cartridges, originals and non-originals and there are 2 types of non-originals being compatibles and remanufactured (this goes for inks also as does the information below). Otherwise known as non genuine, after market this is how they work:-
- Compatibles are actually a brand new cartridge manufactured to work in the same way (without breaking the trademark, copy protection laws) as the same original cartridge with the same machines. The benefit you gain from these is obviously cost savings with at times massive savings up to around 50%. The downside is they are not as environmentally friendly as remanufactured toners and there are the occasional failures and complaints about lower quality (though failure rates for the top companies making these are within industry norms and not significantly higher than those of the original manufacturers themselves)
- Remanufactured toners however are a little different as they take an empty original (it should have only been used ONCE) and fill it with toner. As long as you buy from a reputable retailer it will have also been checked to determine if parts need to be replaced as well as toner refilled. You also get good cost savings as you do with compatibles but the environment wins out big time as you helping ‘close the loop’ by reusing an empty original. Once again the same applies as above with quality and failures (both negligible in my experience as a retailer in this industry).
NOTE: Its worth making a special note here that disposing of empty toners is a problem worldwide as the plastic they’re made of takes so long to break down and the toxicity of the toner inside. In many countries today there are programs available where you can get rid of your empties without just throwing them in the bin. In fact if you hunt around you’ll probably find a company will pay you for them as they need a constant stream of empties coming through so they can remanufacture them.
Something to keep in mind....
When purchasing a re-manufactured laser toner cartridge, be sure to read the box carefully and ensure you are selecting the right toner cartridge. The first time you purchase a re-manufactured toner cartridge, the box may look entirely different or very plain because these inexpensive toners are often not packaged in fancy, colourful boxes like the name brands. But then they don't cost what the name brand toners do, either.
The bottom line....
If you use a reputable retailer for your home/office supplies they should have a clear policy in place not only about faulty toners but what happens if a cartridge has somehow caused damage to your machine (this would be very unusual by the way). Under these circumstances this policy should give you a full warranty to have the equipment repaired ASAP at no cost to you.
With my clients when they ask what I suggest I always recommend they try a non-original to see for themselves the quality etc. In any case the trick is to be able to make an informed choice with someone you trust so at least if something goes wrong the people you bought from haven’t skipped the country.

Thermal paper possibly be facing high prices at the store.
Thermal paper is impregnated with a chemical that changes color when exposed to heat. It is used in thermal printers and particularly in cheap, lightweight devices such as adding machines, cash registers, and credit card terminals.
The paper is impregnated with a solid-state mixture of a dye and a suitable matrix; a combination of a fluoran leuco dye and an octadecylphosphonic acid is an example. When the matrix is heated above its melting point, the dye reacts with the acid, shifts to its colored form, and the changed form is then conserved in metastable state when the matrix solidifies back quickly enough.
Thermal paper is cleaner than your standard ink, produces a crisper resolution, and is ultimately cheaper. Though thermal paper used to be considerably more expensive, the price has come down in recent years, thanks in part to better technology that allows its manufacturers to produce it at a more reasonable cost. Moreover, a thermal paper roll is quieter than bond paper, which is an added bonus for any shopper at the end of a long day.
Appleton uses ideas that make a difference to create product solutions through its development and use of coating formulations and applications, encapsulation technology, and specialized and secure print services. The Company produces carbonless, thermal, security, and performance packaging products. Appleton is headquartered in Appleton, Wisconsin, and has manufacturing operations in Wisconsin, Massachusetts, Ohio, Pennsylvania and the United Kingdom, employs approximately 3,400 people, and is 100 percent employee owned.
When it comes to buying thermal paper, you could possibly be facing high prices at the store. This shouldn't stop you from using this superior product. I've found that it's far easier and more affordable to simply buy your receipt paper rolls and other cash register supplies from online vendors.
In fact, you can find just about all the printing supplies your business needs by shopping online. From register tape to carbonless paper, from printer cleaning accessories to inkjet cartridges, the selection cannot be beat! When you consider the many volume discounts available, it won't make any sense to not stock up on these necessities.

The Lighter Side Of Laptops
This article is about three general categories of light weight laptops. If focuses on thin-and-light laptops, the ultraportables and the tablet PC. The article also provides the reader with basic information about what features usually accompany these categories of laptops.
No matter how convenient, and sometimes absolutely indispensable, it is to be able to take your work around with you travel, at times you can’t help but wish that they’d think of making those laptops a little lighter to carry around.
Well, the good news is that they’ve already thought of that and done something about it too. Today, laptops come is weights as light as two pounds, which makes them an absolute pleasure to carry around.
Lightweight laptops can be broadly classified into three.
Generally a preferred choice among lightweight laptops, the thin-and-light laptops offer powerful mobile processors, are approximately 1 inch in thickness and weigh almost 4 to 6 pounds. The display is usually a widescreen of 12 to 14 inches. They come with a 40 to 80 GB hard drive, an optical drive, networking features like LAN, modem, WiFi and an optional Bluetooth. Popular models among others are the Sharp M4000 and the Toshiba Satellite M55-S325.
The Ultraportables are a good choice for people who need to get their work done between frequent travel. They weigh less than 4 pounds and are less than 1 inch in thickness. With a screen smaller than 12 inches, they also some with a 30-60 GB hard drive, networking options, a touch pad and a small keyboard. Popular models among others are the SONY VAIO VGN-SXP and the IBM ThinkPad T41.
A lot similar in size and weight, to the ultraportable counterpart is the Tablet PC. You can make hand-written notes and navigate using a stylus on its screen. Amazingly small weights, as low as 2 pounds, make this a popular choice among laptop consumers.
However, you might want to keep in mind that what you gain with the portability of lightweight laptops, you might have to give up in terms of keyboards that are less easy to work on, smaller displays and fewer features.
No matter how convenient, and sometimes absolutely indispensable, it is to be able to take your work around with you travel, at times you can’t help but wish that they’d think of making those laptops a little lighter to carry around.

Printers - A Practical Buyers Guide
Buying a printer can be a complicated business, there are more shapes, sizes and types of printers available to the home and small business user than ever before. Printers have also become specialised for their intended purpose.
It is no longer a case of "a printer is a printer". Printers are now designed to be good in a particular area rather than a "Jack-of-all trades", which will do everything.
An often overlooked issue, is the very serious consideration of cost of ownership, which is all about of how much it will cost to keep your printer running (see below). So making that decision on which printer to go for can be a seriously arduous task, especially if you are keen to buy a printer that is not only affordable to buy but also cheap to run.
So here is the information that you need to know and consider, but no one tells you! We have not expanded on which printer is the best at any given time because models constantly change and you can find that information in any current glossy PC magazine off the shelf. Instead, here you will find the good, bad and ugly bits from the different types of printers available so you can make an informed decision yourself.
Inkjet Technology
Inkjet printers form images by spraying tiny droplets of liquid ink onto paper. The size and precision of the dots of ink and the type and quality of the ink itself govern how good the print quality is. A quality inkjet printer can produce very near photo-quality images using specialist photo coated paper. In general there are two types of inkjet printers, those with the printhead built into the printer like Epson, Brother etc and those where the printhead is actually on the ink cartridge like HP and Lexmark. There are many arguments for and against both technologies, but in our experience we have found both to be very good, the major difference seems to be that the cost of running a printer using the "printhead" type ink cartridge is usually higher.
Inkjet ink is specially formulated for specific printer models and their purpose, much technology is involved in the development of these inks to improve print quality, longevity, drying speeds and printing speeds etc. Most inkjet ink is produced using dye based ink which can flow easily through the tiny nozzles of the printhead, this type of ink is good for photos and colour shades but not so good for longevity or solid vibrant colour, think of it like a water colour painting. In recent years pigment ink technology has advanced considerably to enable use in inkjet printing. Previously ink pigments were too large and would block up the nozzles. This type of ink is good for solid colours and longevity, think of it like an oil painting.
Manufacturers like Epson, HP and Jet Tec are now increasingly using a fusion of dye based and pigmented inks to create superb quality photo printing with vibrant colours and longevity too.
Inkjet printers use anything between two and eight ink cartridges to do their job. Generally speaking the entry-level machines use two cartridges, good all round machines use four and specialist photo printers use six or more. The two cartridge system works fine though can be a bit wasteful on the colour ink, so go for a four-cartridge system where possible especially if you do colour printing. The six or more cartridge systems produce outstanding photos, but can be costly and a pain to keep changing cartridges (printer does not work if any one cartridge is empty).
Inkjet printers are the best solution for most people and are usually the most cost effective way to print - unless you are printing large volumes.
Portable Inkjet Printers
These printers are small, lightweight and ideal for people on the move. Although the printing of high quality photographs is usually beyond this type of printer, basic colour printing is of good quality and the quality of text print is mostly outstanding considering the size of these tiny portable A4 printers. These printers are not suitable for high volume printing.
Inkjet Printers
The Inkjet Printer is the most commonly used type of printer among home and small business users. With excellent all round printing capabilities, from black & white text print and good colour prints through to very hi-resolution, high quality photographs using Inkjet Photo Printers. Inkjet printers are available from cheap entry level to high-end business use machines and can print from photo size prints to massive A2 and bigger sizes, there are models for occasional use and others for high volume print jobs too. One of the many great things about Inkjet printers is that you can use a wide variety of media to print on, including standard paper, photo paper, card, t-shirt transfers, canvas, projector film etc, achieving different looks and textures for your prints and print for different purposes. Most Inkjet printers are USB connections and not suitable for networks, although models are also available for networks and with parallel connections.
Multi-Function Inkjet Printers
Multi-Function Inkjet Printers have been built to meet the needs of home offices and small businesses. These excellent value machines provide multiple solutions in one compact and easy to use machine i.e. printing, scanning, copying and some also have built in fax machines too. Not only are these machines great for saving space on your desk, but they are also very good for printing too using the same technology as standard inkjet printers. The only thing you should be aware of is that you can only use one function at a time and if anything goes wrong with an "All-in-one" machine, you may lose the all the functions at once!
Laser Printers
Laser printers work in a similar way to photocopiers, except they use a laser instead of a bright light to scan with. They work by creating an electrostatic image of the page onto a charged photoreceptor, which in turn attracts toner in the shape of an electrostatic charge. Toner is the material used to make the image (as ink is in an inkjet printer) and is a very fine powder, so laser printers use toner cartridges instead of ink cartridges.
Laser Printers have traditionally been the best printing solution for heavy office users as they produce a very high quality black text finish and offer relatively low running costs. However, laser printers have advanced a great deal recently and their prices have steadily dropped, as a result there are now compact laser printers, multi-function and colour laser printers all at very affordable prices. Laser printers make sense if you need to do a lot of high quality black or colour prints, not photos. The great thing about a colour laser printer is that they can print a very good quality colour image on standard copier paper, so you do not need to use expensive photo paper for large jobs. Do check the prices of the consumables before you buy the printer as these can be very expensive for colour laser printers.
Laser printers are the best solution for people who are printing in large volumes, that is, in 100's of pages at a time or 1000's of pages per month. Colour lasers also take quite a while to warm up, so are not ideal for printing single pages.
Solid Ink Printers
Solid ink printers use solid wax ink sticks in a "phase-change" process, they work by liquefying wax ink sticks into reservoirs and then squirting the ink onto a transfer drum from where it is cold-fused onto the paper in a single pass. Solid ink printers are marketed almost exclusively by Tektronix / Xerox and are aimed at larger businesses and high volume colour printing.
Solid ink printers used to be cheaper to purchase than similarly specified colour lasers and fairly economical to run owing to a low component usage, today it is not necessarily any cheaper than a colour laser printer. Output quality is good but generally not as good as the best colour lasers for text and graphics or the best inkjets for photographs. Print speeds are not as fast as most colour lasers.
Dye-Sublimation Printers
Dye-Sublimation printers use heat and solid colour dyes to produce lab-quality photographic images. Dye-Sub printers contain a roll of transparent film made up of page-sized panels of colour, with cyan, magenta, yellow, and black dye embedded in the film. Print head heating elements vaporize the inks, which adhere to a specially coated paper, as the ink cools it re-solidifies on the paper. Colour intensity is controlled by precise variations in temperature.
Dye-sublimation printers lay down color in continuous tones one color at a time instead of dots of ink like an inkjet, because the colour is absorbed into the paper rather than sitting on the surface, the output is more photo-realistic, more durable and less vulnerable to fading than other ink technologies.
The downside of Dye-Sub printers is that they are generally more expensive to buy and run, usually limited to photo sized prints only and can only print onto one type of specialised paper as well as being quite slow to print.
Dye-Sublimation printers are best for those who want to link up their digital camera to a purpose built printer and print out the finest quality photos at home without fuss.
Dot Matrix Printers
Dot matrix printers are relatively old fashioned technology today with poor quality print, slow and very noisy output. This type of printer is no longer used unless you wish to create invoices using the continuous paper with holes on both sides. The good thing is that they are very cheap to run!
Cost of Ownership
Many printers today are very cheap to buy, but people are sometimes shocked to discover the cost of replacing the consumables (ink or laser cartridges, imaging drums, fuser, oils, specialist papers etc). The cost of replacing the ink can sometimes cost more than the printer itself! This is one of the most commonly overlooked factors when printers are reviewed and yet one of the most important things to consider before handing over your hard earned cash. Tests run in 2003 by Which? magazine famously compared the cost of HP's ink with vintage 1985 Dom Perignon.
A Sheffield City Council report aimed at helping schools decide on the best-value printers to buy, calculated total cost of ownership over the lifetime of a printer (not sure how long that is!). Adding up all the running costs, ink or toner, paper, maintenance and even electricity, SCC worked out that a colour inkjet costs approx 38p per page to run compared to a colour laser which costs approx 7p per page. Sheffield City Council advised its schools that if they printed more than three colour pages a day (assuming a 40-week academic year) they should buy a laser.
These figures cannot be taken hard and fast due to the many variables involved, but it is generally accepted that the cost per print of a laser printer is cheaper than that of an inkjet, which is in turn cheaper than that of a sub-dye printer. However, you would have to do a fair amount of colour printing to take advantage of the economy offered by a laser printer.
Summary
When buying a printer, firstly carefully consider its use, is it mostly general printing or for photographs, is it for occasional use or high volumes, will it be a stand alone device or connected to a network? Then using the guideline information above you will be able to decide on which type of printer is most suitable for you at the time.

Network Attached Storage – An Alternative To Tape Back-up
Businesses have been using tape to back up their data since the early days of computing. Tape has its limitations, but it was much cheaper than the alternatives, so its use continued.
Today, the situation is changing. The price of disk storage has come down dramatically and the performance, longevity and use characteristics of disk are far superior to tape. As a result, many businesses are looking to move away from tape for their backup and disaster recovery needs.
The key requirements of an ideal backup scheme are:
• It must be economical. Large amounts of data need to be accommodated (due to the need to keep multiple versions of the data), but in many cases the data will never be accessed. Its contribution to the company’s bottom line only comes if the data is needed, otherwise, it is an unnecessary expense.
• It must be reliable over the long term. Some data must be stored for long periods of time, perhaps decades in some situations, to meet regulatory and business needs. If that data is ever needed it must be readable and accessible. When tape sits unused for a long period, it gets brittle and is prone to breaking and data loss.
• It must be quick and easy to set up and operate. Back-up windows are getting tighter as the hours of operation increase and the amount of data continues to grow. As a result, the speed of the backup is critically important. If the backup process can be automated, human errors and costs are reduced.
• Restoring data, either individual files or a whole system, must be quick, easy and reliable. Today, it can take a long time to retrieve tapes from their offsite storage. Data on tape is stored sequentially so access to specific records can be cumbersome. Reading the tapes can be problematic if the tape is old, brittle or distorted. All this uses precious IT resources that would be better spent elsewhere. Disk storage has none of these issues.
The NAS Approach
With prices in the $2 per GB range, Network Attached Storage (NAS) systems are rapidly becoming the ideal, cost-effective back-up solution.
• Disk-to-Disk data transfer speeds far exceed those of writing to tape, so more data can be backed up in less time.
• Disk storage has greater longevity than tape, so the data is going to be there and accessible when you need it.
• Random access to data on disk saves time when trying to restore specific files.
• NAS devices are independent, complete systems that connect directly to your network so they don’t impact your other systems.
• Tape rotation schemes are possible with disk-based systems and sophisticated ones can eliminate duplicate files for more compact storage.
• For smaller amounts of data, removable disk drives mounted in hot-swap enclosures can provide a competitive alternative for offsite data storage.
• Locating a NAS system in another office and backing it up over the network provides a fast, automated remote backup. In the event of a disaster, the backup system is immediately ready to step in for rapid recovery and business continuity.
Many businesses are implementing a staged approach, where an onsite NAS provides fast backups and restores for servers and workstations. Then, to prepare for a disaster that destroys or prevents access to the primary place of business, the data is automatically replicated to a second NAS at another location. For rapidly changing and highly important data, the on-site and off-site systems can be set up to mirror each other, so that little or no data is lost if disaster should strike.
There are other reasons for deploying a NAS system. By accomplishing multiple goals, the NAS can be even easier to justify. Examples include:
• Additional end user storage. Centralized storage is easier to back up than data stored on many end user systems.
• Ideal for central repositories for workgroup or departmental data that must be shared.
• Regulation compliance, such as email retention requirements for HIPAA or Sarbannes-Oxley.
Even if you decide not to abandon tape backup entirely, you can use a NAS as a rapid staging server to gather the data from other systems quickly during your backup window. Then let the NAS feed the data to the tape unit without worrying about time constraints. This is referred to as disk-to-disk-to-tape backup.
Network Attached Storage systems are quickly becoming the preferred data sharing, management and backup solution for enterprise applications and database environments.
Today, the situation is changing. The price of disk storage has come down dramatically and the performance, longevity and use characteristics of disk are far superior to tape. As a result, many businesses are looking to move away from tape for their backup and disaster recovery needs.

Data on tape is stored sequentially so access to specific records can be cumbersome. Reading the tapes can be problematic if the tape is old, brittle or distorted. All this uses precious IT resources that would be better spent elsewhere. Disk storage has none of these issues.
The NAS Approach
With prices in the $2 per GB range, Network Attached Storage (NAS) systems are rapidly becoming the ideal, cost-effective back-up solution.
• Disk-to-Disk data transfer speeds far exceed those of writing to tape, so more data can be backed up in less time.
• Disk storage has greater longevity than tape, so the data is going to be there and accessible when you need it.
• Random access to data on disk saves time when trying to restore specific files.
• NAS devices are independent, complete systems that connect directly to your network so they don’t impact your other systems.
• Tape rotation schemes are possible with disk-based systems and sophisticated ones can eliminate duplicate files for more compact storage.
• For smaller amounts of data, removable disk drives mounted in hot-swap enclosures can provide a competitive alternative for offsite data storage.
• Locating a NAS system in another office and backing it up over the network provides a fast, automated remote backup. In the event of a disaster, the backup system is immediately ready to step in for rapid recovery and business continuity.
Many businesses are implementing a staged approach, where an onsite NAS provides fast backups and restores for servers and workstations. Then, to prepare for a disaster that destroys or prevents access to the primary place of business, the data is automatically replicated to a second NAS at another location. For rapidly changing and highly important data, the on-site and off-site systems can be set up to mirror each other, so that little or no data is lost if disaster should strike.
There are other reasons for deploying a NAS system. By accomplishing multiple goals, the NAS can be even easier to justify. Examples include:
• Additional end user storage. Centralized storage is easier to back up than data stored on many end user systems.
• Ideal for central repositories for workgroup or departmental data that must be shared.
• Regulation compliance, such as email retention requirements for HIPAA or Sarbannes-Oxley.
Even if you decide not to abandon tape backup entirely, you can use a NAS as a rapid staging server to gather the data from other systems quickly during your backup window. Then let the NAS feed the data to the tape unit without worrying about time constraints. This is referred to as disk-to-disk-to-tape backup.
Network Attached Storage systems are quickly becoming the preferred data sharing, management and backup solution for enterprise applications and database environments.
Maintaining your Mac
Mac and the OS X are very stable and reliable. However, if you want your Mac to work perfectly you have to maintain it properly. Most of the errors and glitches that happen to your mac are caused by incorrect permissions table. Mac OS X as a UNIX based system has a UNIX way of handling the files. UNIX as a multi-user system has a special way of manipulating file access. (More about file permissions you can read here). When the new software is installed on your Mac or you did some other system tweaks, it's very likely that permissions will mess itself up so you wont be able executing applications or it may happen that your mac is acting weird. The easiest way of fixing permissions is by using Mac OS X "Disk Utility" which can be found in /Applications/Utilities folder.
Fixing permissions is recommended before and after installing any software to your mac as well as installing any software updates. There are various software available on the Internet to help you keep your Mac maintained and in a "good health". Software such as Onyx or Cocktail are doing a great job by not only repairing and verifying permissions for you but also cleaning the internet history,cache,temporary files and running optimization scripts.
If you for some reason are unable to boot your system,before you do anything like re-installing the OS, try pressing command + S on the system boot-up and it will get you into console mode. Type in /sbin/fsck -fy and hit enter. Do that couple of times until it doesn't say "System Modified". Before you use "fsck" command, I advise you to open terminal, type in man fsck and read the manual page carefully. Not all software errors are as easy to fix by using methods above. Some errors and system misbehaving can indicate serious hardware failure so if the problems persist, the best is to take your mac to an authorized Apple service for a check-up.

IT Consultants: Desktops, Notebooks and PDAs as Profit Centers
If you’re one of those IT consultants who breaks out in hives at the thought of getting your hands dirty with low-margin sales of desktop PCs, notebooks or PDAs, you may not be looking far enough beyond the box. In this article, we’ll look at how to profit from your clients’ needs for full-service support of desktops, notebooks and PDAs.
IT Consultants Roles as Technology Influencers
IT consultants who have been in business awhile already know that smart PC hardware selection can make installation, support, troubleshooting and upgrading work much easier.
Selecting the right PCs and related peripherals can dramatically boost system reliability, which helps to keep your valued clients happy. Pick the wrong PC hardware and well, let’s not even go there! When PC hardware starts acting up, clients get peeved . . . and clients may actually “blame” your IT consultants for their IT-related problems.
As a general rule of thumb, it’s a good idea to stay on the “good” side of the folks that authorize your service agreements and sign your big retainer checks.
New Advances in Technology
Despite all the advances during the past few years, the venerable desktop, notebook and server have remained the staples of the PC hardware world. Sure, there are newcomers. Since the mid-‘90s, both Palm and Microsoft have spearheaded competing handheld standards. But the main PC hardware world has not seen much change by IT consultants.
And now there are special-purpose rack-mountable servers, with surely more to come, dedicated to the unique demands of serving high-volume Web sites.
IT Consultants Have a Huge Profit Opportunity with Hardware Sales
IT consultants play an extremely important role as your clients’ primary technology influencer – the one who recommends what to buy. This responsibility presents a huge business opportunity for IT consultants with desktops, notebooks and PDAs.

How to replace your iPod Battery
iPods are a great invention, however many have complained about the lack of playtime and poor battery life. Previously, replacing an iPod battery was next to impossible. So when your battery dies, its time for a new iPod. This of course proved to be extremely expensive. As a result, manufacturers have begun producing aftermarket iPOD batteries for a DIY conscious producer. There are even high capacity batteries that will basically give you more playtime on your iPod in comparison to the original iPod batteries. An even better incentive to replace that dying battery!
I know what you’re thinking, you don’t want to rip apart that shiny iPod of yours! Aftermarket iPod batteries were designed to make the installation as simple as possible (it wasn’t really all that difficult to begin with anyway). Since the batteries installation doesn’t require any soldering, the most difficult part is opening up the physical case. Since the iPod doesn’t contain any screws, the casing must be pried off in order to access the internal battery. I do not recommend using a screwdriver to do this as it will damage the case. A guitar pick has been recommended to do the job, but even better, some batteries come with the non scratch nylon tools required to open your iPod safely.
Below are some instructions on how to install your battery. I am aware that there are more than one
Steps to install the battery:
• Lay your iPod on a piece of cloth o non scratch surface. Using your non scratch tools, slowly insert it under the cover and begin to pry off the cover. You should hear it begin to open. Work your way by sliding the tool all around the edges.
• The iPod is basically made of two halves. With both halves separated, put the empty shell aside.
• The other half will have all the internal components in there. You should be able to spot the battery in there. You will see that the battery is connected to the main circuit board of your iPod. Carefully unplug the old battery by pulling on the end of the connector.
• Get your new battery and plug in into the connector socket on your iPod’s circuit board. The connector will only go in one way so do make sure you insert it the right way up.
• Once it’s all connected up, put the cover back on by pressing the edges of the two halves together.
• Plug your charger in and let your new iPod charge up for at least 4 hours. All new batteries should get a longer than normal charge the first time around.
• Now you’re ready to enjoy your music once more!

How Platespin Server Consolidation Works
It is no secret that servers can take up a lot of floor space, and power. As a result, they can sometimes seem inconvenient. One way to save space and power is to consolidate servers. Server consolidation is very important in order to ease some of the frustrations of overdue consolidation processes. Server consolidation projects can also be accelerated via automation and virtualization. Platespin server consolidation helps to accelerate consolidation projects, and reduce errors. This is done without actually having to have contact with the physical machines.
Platespin allows managers to measure and evaluate resource utilization in order to speed up capacity planning for consolidation projects. This is accomplished by remotely gathering information about the server. This information can be the server operating system, memory, CPU speed, the network, and memory. Platespin server consolidation works on Windows NT, 2000, and 2003 systems. The system works without the help of agents. Therefore, the need to manually deploy software is eliminated. The risk of missing certain agent dependencies is also eliminated in this case. Platespin is also very simple and lightweight, so it can start to collect data in almost one minute.
Platespin completely automates the physical to virtual migration of data. This allows the servers to be consolidated quickly and with more ease. There is a drag and drop interface that allows the user to convert machines running Windows or Linux into one fully functional virtual machine that is hosted on several types of servers. These servers include VMware GSX Server, Microsoft Virtual Server 2005, or simply a Platespin Flexible Image file.
Network configurations, CPU cycles disk space, and memory allocations can all be converted rather quickly. This ease allows users to right-size target servers as the conversion process is occurring. As a direct result, data centers are made able to increase the number of servers that are able to be consolidated. This further optimizes resource utilization rates.
Sever consolidation may seem complicated, but the right program can make it quite simple. Platespin automates many processes and allows many different factors to be converted quickly. This means that the total time for consolidating servers is reduced.

Hardware: Now What Exactly Are We Talking About?
Now just because this article is on the internet doesn’t mean that the hardware that we’re talking about has anything to do with computers! I mean that is probably the case but why don’t we remain patient and civilized and find out before we start jumping the gun and squawking about hard drives and monitors and video cards and CPUs and the like. Lets take a minute to consider what else we could be talking about and make sure it isn’t those things before we proceed any further down the computer path.
Hardware could be ACE or The Home Depot right? I mean after all most retail stores today are trying to maximize their market share and are therefore making available many services including a large part of their inventory online. So maybe you are looking for a new compound miter saw or some 35 year guaranteed shingles. Maybe you want to replace that old squeaky screen door. Maybe you have a leak in your plumbing that needs immediate attention. Well you are going to have to stay tuned because I may be able to help you.
Within the above category of hardware there is another category of hardware that refers to the handles on drawers and doors. This is a surprisingly popular market sector as shows like trading spaces, extreme makeover, and Martha Stewart’s Home show. People, especially with the economy being rather slow, have decided that instead of getting new things that they will just make due with their old cupboards, or doors, or desks, or dressers, etc. But they are willing to spruce them up by refinishing them and adding new, more generationally acceptable, knobs that match the simple yet elegant and refined look of today. Silver not gold; brushed or “antique” finish rather than a chrome shine.
Ok, ok so I am talking about computer hardware I just wanted to let you know that this may not be what everyone else is referring to when they are talking about hardware in an article on the internet. Any this is a great time for those struggling with their computer components. Online support is getting more and more useful and soon you won’t have to ever take your computer anywhere to have it fixed. A technician will be able to analyzed, diagnose, and correct problems over the internet and you will be on your way without much bother at all. Sounds good doesn’t it?

Flash USB Drives: Backup Easily, Conveniently And Securely
Tired of switching CD/DVD discs while backing up? Flash USB drives to the rescue!
If you already backup often, you are doing the most you can to secure your files against accidental file deletion and recovery, file damage and what not. Also, you may be considering making your backups as easy and painless as possible. So what may be a remedy to this issue?
Naturally, you need to consider several backup media and select the one suitting your needs and requirements. Among all, CD, DVD and flash USB drives are considered.
You may as well use CD to backup, but you will either need to dump CD-R discs often, or insert a CD-/+RW discs often to make another backup. Someone else can also misplace your backup CD disc or overwrite your backup data with other information. Moreover, a CD only admits about 700Mb of data, which may not be convenient. Nor is storing multiple CDs of your backup copy.
The same can be said about backing up to DVD. Of course, a DVD admits from 4.7Gb to about 18.6Gb of data, but is it really convenient backing up to DVD? An external hard disk drive or a flash USB drive will be speedier, more reliable and easier overall.
Here is when a flash USB drive comes handy. It not only allows faster data copying than CD or DVD, but can also admit from 256Mb to 4Gb of data (or maybe more). Moreover, you can take the USB drive with you anywhere you go and transfer the data between distant computers without resolving to FTP backup. Of course, one of the drawbacks of a flash USB backup is that the drive is only limited to about 100 000 writings, while another slight disadvantage (or an advantage, if you put it nicely) is that the device is so small you can easily misplace it.

Device Drivers
Not many people know about device drivers until they need to find one, be it for a printer or most commonly a modem driver. Finding one can be very difficult to say the least if you are using HSP based modem drivers.
What is a Device Driver?
Every device, be it be a printer, modem, or keyboard, must have a driver program. Many device drivers, such as the keyboard driver, come with the operating system. For other devices, you may need to load a new driver when you connect the device to your computer. Note that in the older DOS systems, drivers are files with a.SYS extension. now in Windows environments, drivers often have a.DRV extension.
What do they do?
A device driver is nothing more than a glorified translator which fits between the device and programs that use the device. Each device be it a modem or printer has its own set of commands that only its driver knows. That bieng said, however most programs access devices by using generic commands. The device driver, therefore, accepts generic commands from a program and then translates them into specialized commands for the device.
Finding them:
Finding a driver can be very difficult as most manufactures manufacture a device and after 2 or 3 years change and make a different version. Finding a driver for your device becomes a task as the manufactures remove the drivers from their website and refuse to support them. They hope that you will upgrade to their new line of products, but there is no need if you know where to find your drivers. Try the following website which not only has more than 2,000 drivers but finds what you are looking for, free.
Remember, don't upgrade unless you want to. There is no need to buy new, when the old printer or modem worked just fine!
