Description
PostScript is a page description language produced by Adobe Systems Inc. since the early 1980’s. Adobe was formed in 1982 by Dr. John E. Warnock and Dr. Charles M. Geschke. It provides a verbose language of instructions to describe a page of information. While it requires more memory to work with than most page description languages, it was the first widely available product that allowed for control over a large number of fonts and graphical objects.
The first version published in 1985 (the old Red Book) is called Level I, the current implementation (the big Red Book) is called Level II (do not mix these levels with the PostScript version a printer supports, e.g. version 47.0 or version 2011.110, nor with the number in the begin line of any PostScript output like “%!PS-Adobe-3.0”). The PostScript level and to an extent the version of the interpreter too, define the possible operations. For more information see the Red and White Book.
There are several PostScript clones around because of the costly licensing fees for Adobe’s interpreter, the best-known surely is GhostScript. Others, built directly into laser printers or addable via cartridges, are Phoenix Page, Brotherscript, Page Styler, True Image, Turbo PS, PDL and KPDL. Naturally they all claim to be 100% PostScript compatible, but this compatibility sometimes ends when it comes to font downloading, font manipulation like adding a metric table or adding new characters, or some other operations. The printing of simple text and graphics is usually no problem with these clones.
