[gs-devel] upcoming freeze for the 8.63 release - Make CUPS filters/PPDs PDF ready

[Till Kamppeter]

What I would like to have in GhostScript 8.63 is that the included CUPS 
filter scripts and PPDs (in cups/ directory) get prepared for PDF as 
standard print job format. This would mean that they should either 
understand both PostScript and PDF (the better solution) or there should 
be two sets of filters and PPDs, one for PostScript and oe for PDF. In 
the first case (understanding both languages) the PPDs should have two 
cupsFilter lines

*cupsFilter:    "application/vnd.cups-postscript 100 pstopxl"
*cupsFilter:    "application/vnd.cups-pdf 0 pstopxl"

with the cost factor being in favour of PDF. As Ghostscript understands 
both PostScript and PDF we could probably stay with one filter (here 
pstopxl, we should consider renaming to pdltopxl).

Now my problem is how the options in the PPD have to be defined. Most of 
them are PostScript commands to be added to the data stream, but what 
happens if the data stream is PDF? Anyone has an idea how to do this 
correctly?
