Foomatic is a printing system designed to make it easier to set up
 common printers for use with Debian (and other operating systems).
 It provides the "glue" between a print spooler (like CUPS or lpr) and
 your actual printer, by telling your computer how to process files
 sent to the printer.
 .
 This package contains all PPD files which can be generated from the Foomatic
 database as one small compressed archive. This reduces the disk space
 consumption compared to the Foomatic XML database vastly and in addition
 makes listing of all available PPDs and extracting the needed PPD much faster
 than using the Foomatic XML database.
