foomatic-rip --ppd <ppdfile>[-J<jobtitle>] [-Z<option>=<value>[,<option>=<value>[, ...]]
It translates PostScript (and also other file formats) from standard input to the printer's native language (usually put to standard output).
The translation is done with an external renderer, usually GhostScript (gs(1)). If no translation is needed (PostScript printer) the renderer's command line reduces to cat(1). The way how this translation is done is described in a PPD file.
Printer capabilities, how to handle user options, and how to build the renderer command line is always described by PPD files, these PPD files can come from Foomatic or can be the ones supplied by the manufacturers of PostScript printers. The PPD files are the same for all spoolers.
foomatic-rip works with every known spooler (CUPS, LPRng, LPD, GNUlpr, PPR, PDQ, CPS, and without spooler). It auto-detects the spooler from which it was called by the command line options and environment variables which were supplied by the spooler.
Non-PostScript files are translated to PostScript before they are passed to the renderer. This is usually done by a2ps(1), enscript(1), or mpage(1). foomatic-rip auto-detects which program is installed, but manual configuration is also possible.
foomatic-rip does not only apply option settings supplied by the user through the command line of the printing command, but also searches the entire job for embedded option settings (only PostScript jobs). Here not only settings affectimg the whole job are taken into account, but also settings in the page headers, which are only valid for the page where they were found, so applications which produce PostScript code with page-specific printer option settings are fully supported.
foomatic-rip -P <printer> -o docs <file>
(<file> can be an arbitrary existing file, as .bashrc, will not be printed) to print a list of available options for the specified <printer>.
foomatic-rip will print from standard input unless a file to print is specified on the command line. If your printer PPD file is stored as /etc/direct/<printer>.ppd or ~/.foomatic/direct/<printer>.ppd you can use it by simply specifying "-P <printer>".
Put a line
*FoomaticRIPPostPipe: "| <command>"
into the PPD file, right after *PPD-Adobe: "4.3", where <command> is a command into which you wnat to re-direct the output data. Due to the restrictions of PPD files <, >, and " are not allowed in the <command>, replace them as follows:
Character Replacement ---------------------
This way you can print directly to your printer, use
*FoomaticRIPPostPipe: "| cat > /dev/lp0"
*FoomaticRIPPostPipe: "| cat > /dev/usb/lp0"
for local parallel or USB printers. To make normal users able to print this way add them to the group lp and make sure that the appropriate printer device file /dev/... is group-writable for the lp group.
for a TCP/Socket/JetDirect printer with the host name printer listening on port 9100 you need this:
*FoomaticRIPPostPipe: "| /usr/bin/nc -w 1 printer 9100"
Note the "-w 1" in the "nc" command line, it makes "nc" exiting immediately after the data is transferred to the printer.
*FoomaticRIPPostPipe: "| rlpr -Plp@printserver"
directs your jobs to the LPD printer queue lp on the machine named printserver.
