[ L. postscriptus, ( assumed) p. p. of postscribere to write after; post after scribere to write: cf. F. postscriptum.

Martin Newell) at {XEROX PARC}, and finally implemented in its
current form by John Warnock et al. after he and Chuck Geschke
founded {Adobe Systems, Inc.} in 1982.
PostScript is an {interpreted}, {stack-based language} (like
{FORTH}). It was used as a page description language by the
{Apple LaserWriter}, and now many {laser printers} and
on-screen graphics systems. Its primary application is to
describe the appearance of text, graphical shapes, and sampled
{images} on printed or displayed pages.
A program in PostScript can communicate a document description
from a composition system to a printing system in a
device-independent way.
PostScript is an unusually powerful printer language because
it is a full programming language, rather than a series of
low-level escape sequences. (In this it parallels {Emacs},
which exploited a similar insight about editing tasks). It is
also noteworthy for implementing on-the fly {rasterisation},
from {Bezier curve} descriptions, of high-quality {fonts} at
low (e.g. 300 dpi) resolution (it was formerly believed that
hand-tuned {bitmap fonts} were required for this task).
PostScript's combination of technical merits and widespread
availability made it the language of choice for graphical
output until {PDF} appeared.
The {Postscript point}, 1/72 inch, is slightly different from
other {point} units.

PostScript: n. A page description language, based on work originally done by John Gaffney at Evans and Sutherland in 1976, evolving through ‘ JaM’ (‘ John and Martin’, Martin Newell) at XEROX PARC, and finally implemented in its current form by John Warnock et al. after he and Chuck Geschke founded Adobe Systems Incorporated in 1982. PostScript gets its leverage by using a full programming language, rather than a series of low- level escape sequences, to describe an image to be printed on a laser printer or other output device ( in this it parallels EMACS, which exploited a similar insight about editing tasks). It is also noteworthy for implementing on- the fly rasterization, from Bezier curve descriptions, of high- quality fonts at low ( e. g. 300 dpi) resolution ( it was formerly believed that hand- tuned bitmap fonts were required for this task). Hackers consider PostScript to be among the most elegant hacks of all time, and the combination of technical merits and widespread availability has made PostScript the language of choice for graphical output.
