'''Display PostScript''' (or '''DPS''') is a [[2D computer graphics|2D graphics engine]] system for computers that uses the [[PostScript]] (PS) imaging model and language to generate on-screen graphics. PS was originally developed for [[computer printing]], to which DPS adds a number of features intended to ease working with [[bitmap]]ped displays and improve performance of some common tasks.

Early versions of PostScript display systems were developed at [[Adobe Systems]]. During development of the [[NeXT]] computers, NeXT and Adobe collaborated to produce the official DPS system, which was released in 1987. NeXT used DPS throughout its history, while versions from Adobe were popular on Unix workstations for a time during the 1980s and 1990s. The [[SunOS]] [[NeWS]] window system used DPS from the end of the 1980s into the 1990s.
