====Impact printers====
{{anchor|Impact_printers}} Impact printers rely on a forcible impact to transfer ink to the media. The impact printer uses a print head that either hits the surface of the ink ribbon, pressing the ink ribbon against the paper (similar to the action of a [[typewriter]]), or, less commonly, hits the back of the paper, pressing the paper against the ink ribbon (the [[IBM 1403]] for example). All but the [[dot matrix printer]] rely on the use of ''fully formed characters'', [[letterform]]s that represent each of the characters that the printer was capable of printing. In addition, most of these printers were limited to monochrome, or sometimes two-color, printing in a single typeface at one time, although [[emphasis (typography)|bolding]] and [[underlining]] of text could be done by "overstriking", that is, printing two or more impressions either in the same character position or slightly offset. Impact printers varieties include typewriter-derived printers, teletypewriter-derived printers, daisywheel printers, dot matrix printers, and line printers. Dot-matrix printers remain in common use <ref>{{cite web| url = https://www.printersbuddy.com/uses-of-printer/| title = Uses of Printer?| work = PrintersBuddy.com| access-date = 7 June 2022| archive-date = 17 January 2023| archive-url = https://web.archive.org/web/20230117222607/https://www.printersbuddy.com/uses-of-printer/| url-status =
