Foomatic

Foomatic is a configurable printing filter. It uses PPD files as configuration to generate appropriate output for a given printer. It is spooler independent which means it can be used with Common Unix Printing System (CUPS), LPRng and others.[1] It uses Ghostscript in the background, using options according to the PPD file of the printer. Currently it is developed by the OpenPrinting workgroup of the Linux Foundation.

Linux/Unix printing process. The foomatic filter is applied when conversion from PostScript to raster takes place.

Operation

Like CUPS, foomatic supposes that applications will produce output in PostScript. If the output spools to a PostScript printer, no further action is needed. Otherwise, the most generic way to act is:

  • Create a raster file from the PostScript (ps2raster, usually using Ghostscript in the background)
  • Create a printer-language file from the raster data (raster2xxx, using the raster driver of the target printer)
  • Send the printer-language file to the printer

But if foomatic-rip "knows" about the available printer, it will translate the PostScript data directly to the printer's language, without creating the intermediate raster file.

Description of the package

The components of the package are:

foomatic-filters (or "foomatic-rip")
It transforms PostScript data to raster (or to the printer's native language), using the PPD as configuration. It needs a low level driver (specific to each printer) to generate the final code.
foomatic-tools
foomatic-db-engine: A tool that generates PPD files from the data in Foomatic's database. It also contains scripts to directly configure print queues and handle jobs.
foomatic-db: The collected knowledge about printers, drivers, and driver options in XML files, used by foomatic-db-engine to generate PPD files.
foomatic-db-hpijs: Foomatic XML data generators for HP's HPIJS driver.

Free drivers that can interface with foomatic
