Its first version appeared in the early 70s on BSD &UNIX; and was formally described in <ulink url="http://www.rfc.net/rfc1179.html">RFC 1179</ulink> only as late as 1990. At the time when BSD "remote" printing was first designed, printers were serially or otherwise directly connected devices to a host (with the Internet hardly consisting of more than 100 nodes!); printers used hole-punched, continuous paper, fed through by a tractor mechanism, with simple rows of ASCII text mechanically hammered on to the medium, drawn from a cardboard box beneath the table. It came out like a zig-zag folded paper "snake". Remote printing consisted of a neighbouring host in the next room sending a file asking for printout. How technology has changed! Printers generally use cut-sheet media, they have built-in intelligence to compute the raster images of pages after pages that are sent to them using one of the powerful page description languages (PDL). Many are network nodes in their own right, with CPU, RAM, a hard disk and their own Operation System, and are hooked to a net with potentially millions of users... It is a vast proof of the flexible &UNIX; concept for doing things, that it made "Line Printing" reliably work even under these modern conditions. But time has finally come now to go for something new -- the IPP. It is strong proof of the flexibility of &UNIX;; that "Line Printing" works reliably, even under these modern conditions.

                        <glossdef><para>Already years ago, when Linux printing was still really difficult (only command line printing was known to most Linux users, no device specific print options were available for doing the jobs), Grant Taylor, author of the "Linux Printing HOWTO", collected most of the available information about printers, drivers and filters in his database. With the emerging &CUPS; concept, extending the use of PPDs even to non-PostScript printers, he realised the potential of this database: if one puts the different datablobs (with content that could be described along the lines "Which device prints with which Ghostscript or other filter?", "How well?", and "What command line switches are available?") into PPD-compatible files, he could have all the power of &CUPS; on top of the traditional printer "drivers". This has now developed into a broader concept, known as "Foomatic". Foomatic extends the capabilities of spoolers other than &CUPS; (LPR/LPD, LPRng, PDQ, PPR) to a certain degree ("stealing" some concepts from &CUPS;). The Linuxprinting Database is not a Linux-only stop -- people running other &UNIX; based OSes (like *BSD or &MacOS; X) will also find valuable information and software there. </para>

A RIP may or may not be located inside a printer. For many &UNIX; systems, Ghostscript is the package that provides a "RIP in software", running on the host computer, and pre-digesting the &PostScript; or other data to become ready to be sent to the printing device (hence you may perceive a "grain of truth" in the slogan "Ghostscript turns your printer into a &PostScript; machine", which of course is not correct in the true sense of the meaning).</para>
