Title:
  PDF workflow flawed, crashes printers

Status in ghostscript package in Ubuntu:
  Fix Released
Status in ghostscript source package in Lucid:
  Won't Fix

Bug description:
  Binary package hint: cups

  Under Ubuntu Lucid, the new PDF workflow in CUPS poses various
  problems for various printers: jobs will either not print (and may
  crash the printer) or print "very slowly". These are reports from
  various customers.

  We have seen a bunch of Ricoh printers fail (killing the user
  interface of the printer, a hard reset is necessary to be able to use
  the printer again); notably a Ricoh Aficio AP4510 PS that crashes; and
  a Ricoh1224c that sometimes does not print; a Panasonic printer,
  DP-C265 (printing will sometimes suddenly reset the printer); but also
  other customers complain about not being able to print anymore, on
  various brands of printers (we've seen Brother and HP)

  We heavily suspect the new PDF workflow in CUPS, as the following workaround works:
  change /usr/share/cups/mime/mime.convs to say:
  application/pdf                 application/vnd.cups-postscript 43      pdftops
  application/postscript          application/vnd.cups-postscript 65      pstops

  This, essentially, makes the workflow use Postscript again when either
  PDF or Postscript is presented.

  Unfortunately, a crashing printing interface does not normally tell
  why it is crashing, so I suspect this bug to be quite hard to dig
  further into. Somewhere between pstopdf, pdftopdf and cpdftocps,
  something goes wrong. It may even be the file size (but I couldn't
  find any size information in the ipp backend log messages that Cups
  sends out with debug-logging enabled).

  There are many bugs that may be related to this: bug #655422 (Sending
  pdf and ps files to a printer routinely fails), Bug #665978 (Slow
  Printing), Bug #667102 (Printing errors after upgrade).
