In computing, an output device for producing printed copies of text or graphics. Types include the daisywheel printer, which produces good-quality text but no graphics; the dot matrix printer, which produces text and graphics by printing a pattern of small dots; the ink-jet printer, which creates text and graphics by spraying a fine jet of quick-drying ink onto the paper; and the laser printer, which uses electrostatic technology very similar to that used by a photocopier to produce high-quality text and graphics.

Printers may be classified as impact printers (such as daisywheel and dot matrix printers), which form characters by striking an inked ribbon against the paper, and non-impact printers (such as ink-jet and laser printers), which use a variety of techniques to produce characters without physical impact on the paper.
