If the application cannot do it,
see "Printing from Mozilla" at
http://en.opensuse.org/SDB:Printer_Configuration_from_SUSE_LINUX_9.1_on
and in
http://en.opensuse.org/SDB:Using_Your_Own_Filters_to_Print_with_CUPS
see
"Optional PCL Printing on PostScript+PCL Printers"
"PostScript Preprocessing with Ghostscript on PostScript Printers"
and perhaps even
"Adding Additional Filter Stages to the Default CUPS Filter System"

Be aware of the drawbacks which are mentioned there
(i.e. don't expect that a workaround is a solution).
