A typesetting device that produces very high-resolution output on paper or film. Imagesetters are too expensive for homes or most offices, but you can obtain imagesetter output by bringing a PostScript file to a service bureau. One reason that PostScript has become the standard for desktop publishing is that nearly all imagesetters support it.
