Editing PostScript (section)

=== Other implementations ===
In the 1980s, Adobe drew most of its revenue from the licensing fees for their implementation of PostScript for printers, known as a [[raster image processor]] or ''RIP''.  As a number of new [[RISC]]-based platforms became available in the mid-1980s, some found Adobe's support of the new machines to be lacking.

This and issues of cost led to third-party implementations of PostScript becoming common, particularly in low-cost printers (where the licensing fee was the sticking point) or in high-end typesetting equipment (where the quest for speed demanded support for new platforms faster than Adobe could provide). At one point,  Microsoft licensed to Apple a PostScript-compatible interpreter it had bought called [[TrueImage]], and Apple licensed to Microsoft its new font format, [[TrueType]].  Apple ended up reaching an accord with Adobe and licensed genuine PostScript for its printers, but TrueType became the standard [[outline font]] technology for both Windows and the Macintosh.

Today, third-party PostScript-compatible interpreters are widely used in printers and multifunction peripherals (MFPs).  For example, [[CSR plc]]'s IPS PS3<ref>{{Citation |title=IPS PS3 |url=http://www.csr.com/products/120/ips-ps3 |archive-url=https://archive.today/20120724005159/http://www.csr.com/products/120/ips-ps3 |archive-date=2012-07-24 |url-status=dead |publisher=CSR}}</ref> interpreter, formerly known as PhoenixPage, is standard in many printers and MFPs, including those developed by [[Hewlett-Packard]] and sold under the [[LaserJet]] and Color LaserJet lines.  Other third-party PostScript solutions used by print and MFP manufacturers include Jaws<ref>{{Citation |title=Jaws |url=http://www.globalgraphics.com/products/jaws-postscript-interpreter/ |access-date=2012-06-13 |archive-url=https://archive.today/20130124020524/http://www.globalgraphics.com/products/jaws-pdf-and-postscript-rip-sdk/ |archive-date=2013-01-24 |url-status=dead |publisher=Global graphics}}</ref> and the [[Harlequin RIP]], both by [[Global Graphics]].  A [[free software]] version, with several other applications, is [[Ghostscript]].  Several compatible interpreters are listed on the Undocumented Printing Wiki.<ref>{{Citation |title=Formats |url=http://www.undocprint.org/formats/page_description_languages/postscript |access-date=2009-12-15 |archive-url=https://web.archive.org/web/20171105214328/http://www.undocprint.org/formats/page_description_languages/postscript |archive-date=2017-11-05 |url-status=dead |contribution=Page description languages: Postscript |publisher=Undocumented Printing |format=wiki}}</ref>

Some basic, inexpensive laser printers do not support PostScript, instead coming with drivers that simply rasterize the platform's native graphics formats rather than converting them to PostScript first.  When PostScript support is needed for such a printer, Ghostscript can be used. There are also a number of commercial PostScript interpreters, such as [[TeleType Co.]]'s ''T-Script'' or [[Brother Industries|Brother]]'s ''BR-Script3''.
