What is: Printer ?

Devices that process data and produce a full-size hard copy of the processed data from computers. There are two types of printers used. The first are impact printers such as line printers, bar printers, chain printers, serial printers, matrix printers, and wheel printers. Non-impact printers, on the other hand, adopt printing principles similar to those used by cathode ray tubes. An example of a non-impact printer is the inkjet printer.
