Page description language of digital printing
In?digital printing, a?page description language?(PDL) is a computer language that describes the appearance of a printed page in a higher level than an actual output?bitmap?(or generally?raster graphics). An overlapping term is?printer control language, which includes Hewlett-Packard's?Printer Command Language?(PCL).?PostScript?is one of the most noted page description languages. The?markup language?adaptation of the PDL is the page description markup language.
Page description languages are text (human-readable) or binary data streams, usually intermixed with text or graphics to be printed. They are distinct from graphics?application programming interfaces?(APIs) such as?GDI?and?OpenGL?that can be called by software to generate graphical output.
