Public bug reported:
Binary package hint: cups
1) Ubuntu release: Ubuntu 9.04 (Jaunty)
2) Package version: cups 1.3.9-17ubuntu3.2
3) What did I expect: PDF generated from printing through cups-pdf saved using
the document title (from %Title in Postscript) as the file name ; it was
working this way in Intrepid.
4) What happened instead: file are always saved as "_stdin_" (literally, and so
overriding each other, but there is a workaround for this) whatever the
document title is.
cups-pdf use the document %Title information to generate the filename
for the PDF to be saved. I discovered that the document entering cups-
pdf processing was lacking this information, while it was available in
the original Postscript document. So it's not a cups-pdf problem but a
CUPS document processing instead.
After investigating more, by putting cupsd LogLevel to debug, I also discovered
that CUPS does process documents aimed at cups-pdf this way:
[Job 380] envp[21]="CONTENT_TYPE=application/postscript"
[Job 380] envp[24]="FINAL_CONTENT_TYPE=application/vnd.cups-postscript"
[Job 380] Started filter /usr/lib/cups/filter/pstopdf (PID 4490)
[Job 380] Started filter /usr/lib/cups/filter/pdftopdf (PID 4492)
[Job 380] Started filter /usr/lib/cups/filter/cpdftocps (PID 4497)
[Job 380] Started backend /usr/lib/cups/backend/cups-pdf (PID 4503)
If I understand correctly, it first cleanup the Postscript code, then
transform it into PDF (?), cleanup the PDF code and transform it back
into Postscript before passing it to cups-pdf. I found that the pstopdf
filter kept the %Title intact but the pdftopdf filter made it lost.
IMHO, but I don't know printing processing well, this is a just a wrong
path for going to cups-pdf. CUPS should just pass it to cups-pdf, after
the minimal Postscript code cleanup and that's it. So this is the
solution I choose to apply at my office: I moved away the file
"/etc/cups/pstopdf.convs" (and restarted the "cups" service) so CUPS
knew no more how to convert from Postscript to PDF. This made my day:
PDF printing was saved using their document title again.
So I declare this as a bug and suggest to take some action (may be mine,
may be a better way) to allow other Ubuntu users to get it right without
having to put their hand in it... ;-)
