Printer

The printer is an output device that puts text and images onto a paper. A
document on the computer is called softcopy while a document which has been
printed onto a paper is called hardcopy.

There are two (2) primary categories of printers:
Impact printer
Non-impact printer

Impact Printer
The impact printer is a printer that prints the characters and images by using pins
or hammers to strike (press) an inked ribbon against the paper. Examples impact
printers are the line printers, daisy Wheel printers, dot matrix, etc.

Non-Impact Printer
A non-impact printer is a printer that uses laser or beam to form texts or

graphics image by spraying ink or transfer marks on the paper without using
ribbon. The most common non-impact printers are ink-jet printers and Laser
Printers.

Laser Printer: These are non-impact page printers. They use laser lights to
produce the dots needed to form the characters to be printed on a page.
