A printer, generally a laser printer, that includes the processing circuitry needed to decode and interpret printing instructions phrased in PostScript. Because PostScript printers require their own microprocessor circuitry and additional random-access memory (RAM) to image each page, they're more expensive than non-PostScript printers. However, they can print text or graphics in subtle gradations of gray. They can also use Encapsulated PostScript (EPS) graphics and outline fonts, both of which you can size and scale without introducing distortions.
