Q. Discuss the various categories of a printer.

Answer :-

Printer: A printer is an output device which is used to generate hard copies (printout) of the output generated by the computer system. The printer can generate both text and images on paper.
Printers are classified as Impact (there is a mechanical contact between printer head and paper) and Non-impact Printers (no mechanical contact between printer head and paper).

The various types of printers are as follows:

• Dot Matrix Printer:- A dot matrix printer (also known as Serial printer) prints one character at a time. It uses dots to create an image. This printer prints characters by striking an ink soaked ribbon against the paper and, hence, is termed as Impact Printer. These printers have low operating costs and can be used to generate carbon copies also.

• Inkjet/Desk Jet/Bubble Jet Printers:- An inkjet printer is the most common type of low-cost printer. It uses the technique of spreading quick dry ink on paper. The ink is stored in the form of cartridges of different colours (red, green, black and yellow). These printers generate high quality prints and are ideal for small offices and homes.

• Laser Printers:- These printers use laser technology to produce printed documents. They are very fast and are used for high quality prints.

• Plotters:- Plotters are output devices that are used for producing good quality images and drawings. Unlike printers, they support printing of large-sized papers. They are mainly used in computer-aided design (CAD).
