Once the ''[[de facto]]'' standard for electronic distribution of final documents meant for publication, PostScript is steadily being supplanted in this area by one of its own descendants, the Portable Document Format or [[Portable Document Format|PDF]]. By 2001 there were fewer printer models which came with support for PostScript, largely due to the growing competition from much cheaper non-PostScript ink jet printers, and new software-based methods to render PostScript images on the computer, making them suitable for any printer (PDF provided one such method). The use of a PostScript laser printer still can, however, significantly reduce the CPU workload involved in printing documents, transferring the work of rendering PostScript images from the computer to the printer. PS is still an option on most "high end" models.
PostScript is a [[Turing-complete]] programming language, belonging to the [[concatenative programming language|concatenative]] group. Typically, PostScript programs are not produced by humans, but by other programs. However, it is possible to write computer programs in PostScript just like any other programming language.

Postscript uses the [[Point (typography)|point]] as its unit of length. However, unlike some other versions of the point, PostScript uses exactly 72 points to the inch. Thus:
