(PDL) A language such as Adobe Systems, Inc.' s PostScript or Xerox' s Interpress whICh allows the appearance of a printed page to be described in a high-level, devICe-independent way. Printing then becomes a two-stage process: an applICation program produces a description in the language, whICh is then interpreted by a specifIC output devICe. Such a language can therefore serve as an interchange standard for transmission and storage of printable documents. (1995-02-20)
