Abbreviated as
PDL, a language for describing the layout and contents of a printed page. The best-known PDLs are Adobe
PostScript and Hewlett-Packard
PCL (
Printer Control Language), both of which are used to control laser printers.
Both
PostScript and modern versions of
PCL are object-oriented, meaning that they describe a page in terms of geometrical objects such as lines, arcs, and circles.
