Page Description Language
     
        (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.
