Pen-based [[plotter]]s were an alternate printing technology once common in engineering and architectural firms. Pen-based plotters rely on contact with the paper (but not impact, per se) and special purpose pens that are mechanically run over the paper to create text and images. Since the pens output continuous lines, they were able to produce technical drawings of higher resolution than was achievable with dot-matrix technology.<ref>{{Cite web|url=http://www.hpmuseum.net/exhibit.php?class=4&cat=24|title=HP Computer Museum|website=www.hpmuseum.net|access-date=10 June 2014|archive-date=3 July 2014|archive-url=https://web.archive.org/web/20140703013250/http://hpmuseum.net/exhibit.php?class=4&cat=24|url-status=live}}</ref>  Some plotters used roll-fed paper, and therefore had a minimal restriction on the size of the output in one dimension. These plotters were capable of producing quite sizable drawings.
