A code or programming language used to specify all elements of the layout of a printed page including fonts, graphic elements and images, in such a way that an interpreter can carry out the necessary printer and control commands in an output device.
A programming language, such as PostScript, that is used to describe output to t printer or a display devioce, which then uses the instructions from the page-description language to construct text and graphics to create the required page image.
A language that describes the contents of a printed page in a higher level than an actual output image. Some page description languages are not complete enough to be considered a programming language, however, PostScript, one of the most widely used page description languages is a very advanced programming language.
A software program used primarily by a multifunctional device or printer to produce a printed page. The PC sends the page description program to the device that used its processing power to run the program and generate the text and/or graphics to be printed on the page. Adobe PostScript(tm) is the most widely used page description language.
a special form of programming language which enables both text and graphics (object or bit-image) to be described in a series of mathematical statements. Their main benefit is that they allow the applications software to be independent of the physical printing device as opposed to the normal case where specific routines have to be written for each device. Typical PDLs include Interpress, imPress, PostScript and DDL.
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.
The format used to describe the position of elements within a page, as well as the page's relative position within a document. The output device then translates the format into a reproduction of the original image.
a program that allows rasterizing output devices such as laser printers and typesetters to output images that may include both text and graphics.
A language that describes some text (which may be enriched with pointers, pictures etc.) and its layout. HTML, PostScript, LaTeX, roff and others are such languages. A file written in those languages is not made to be read as is by a human, but to be transformed (or compiled) into a readable form.
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. Some page description languages are not complete enough to be considered a programming language, however, Post Script, one of the most noted page description languages, is a fully fledged programming language.
