Page Description Language
A page description language (PDL) is a language that describes the appearance of a printed page in a higher level than an actual output bitmap. An overlapping term is printer control language, but it should not be confused as referring solely to Hewlett-Packard's PCL. PostScript, one of the most noted page description languages, is a fully fledged programming language, but many PDLs are not complete enough to be considered a programming language. The markup language adaption of the PDL is the page description markup language.
Page description languages are textual or binary data streams. In principle, the same data stream could be rendered multiple times to generate multiple copies of the same image. They are distinct from graphics APIs such as GDI and OpenGL that can be called by software to generate graphical output.
