Now I turned on debugging. I found interesting things.

..) Some of the .ps files are identified as file type
application/postscript and some as application/pdf .

..) To have all the 'application/postscript' files printed I finally
found an ugly solution. In the last line of
/usr/lib/cups/filters/pstopdf I inserted: 'ps2pdf - - | pdf2ps - - |'.
Now it looks like:

cat "$infile" | $DRMFILTER | ps2pdf - - | pdf2ps - - | $GS
$PS2PDF_OPTIONS $donumcopies $ppd_opts -sOutputFile=- $OPTIONS -c
..setpdfwrite -f -

..) Files of type application/pdf use pdftopdf and this is a binary file
where I can't add some commands. So I am stuck now.

..) Postscript files are converted to PDF and then they seems to be
converted back to Postscript before they are written in pxlmono (or
pxlcolor).


All that shows me that my tries to solve the problem leaded to nowhere.
I still know what's the real cause nor how cups really works.

Could someone help me, please.

Thanks.

Flo.
