In laser printer, for best results you will need to use paper specially designed for toner.
Laser printers use toner rather than ink. The toner cartridges will last much longer and the price per print is very economic
HOW HOW LASER PRINTER LASER PRINTER WORKS?WORKS?
•Laser printing, involves a multistep process, and what’s happening is not obvious from watching the printer operate. Many end users (and even some technicians) see it as a mysterious activity. Paper goes in blank; paper comes out printed. But how does it happen

DOT MATRIX PRINTERSDOT MATRIX PRINTERS
These days, you see less number of dot matrix printers in office environments. However, there are situations where dot matrix printers are still essential, such as when printing on carbon copy forms.
HOW HOW DMP DMP WORKS?WORKS?
Dot Matrix refers to the way the printer creates characters or images on paper. This is done by several tiny pins, aligned in a column, striking an ink ribbon positioned between the pins and the paper, creating dots on the paper.
Characters are composed of patterns of these dots by moving the print head laterally across the page in very small increments
HOW HOW DMP DMP WORKS?WORKS?
The major advantage of the dot matrix printer is that it is versatile. Additionally, dot matrix printers are relatively inexpensive compared to other methods such as laser printing. Finally, dot matrix printers are used when impact on the paper is used to print carbon copies of forms, etc. The Proprinter has nine pins.

The basic principle of a scanner is to analyze an image and process it in electronic way. Image and text capture (optical character recognition or OCR) allow you to save information to a file on your computer. You can then alter or enhance the image.

What you should do What not to do
Use the Start Button on the Windows Taskbar to shutdown your computer. It is also necessary to first save any files you were working with and close all applications running in the taskbar. This is called a clean shutdown. Windows is a program that needs to close, so always use the Start Button.
Don'tSwitch off your computer without shutting down using the Start Button
Keep CD's in a cover and handle them by the edges. Try to keep floppy disks in an a proper storage box and perform a full format on any disk that will hold important data before you use it.
Don'tLeave floppy disks or CD's lying about gathering dust then use them
You should consider cleaning the hardware. Use a small Hoover pipe or an old, stiff paint brush to remove dirt from the motherboard and around the fan. This will help it from over heating.. Use a cotton bud to clean the well. It is fun putting all the keys back without another keyboard to look at.
