Revision as of 05:38, 28 April 2002 by Ray Van De Walker (talk | contribs)(diff) ← Previous revision | Latest revision (diff) | Newer revision → (diff)This is the familiar, inexpensive type of computer printer with a print-head that runs back and forth on the page. Most often it an Ink jet printer or impact printer.
Generally the print-head prints one line of text. It has a single vertical line of dot-making equipment on its print-head.
It produces double-wide characters by printing each vertical slive of a character twice. It produces higher resolutions by printing more slowly. It produces graphics by printing dots, one horizontal character-high stripe at a time.
