[Bug 968785] [NEW] ghostscript runs for indefinitely long period of time when called by foomatic-rip

[Launchpad Bug Tracker]

I am printing to an HP Professional 1102.   In had no success with HPLIP
so am using foo2zjs instead. This works very well when printing from
Libre Office which seems submits data to the print queue as an octet
stream. Printing from evince/chromium/firefox however seems to submit
data to print queue as PDF, which seems to result in a call by foomatic-
rip to gs, which for most jobs other than text with no graphics runs for
an indefinitely long period of time whilst utilising 100% CPU.

I did a "ps -ewf" to see what options gs is being called with and was
able to confirm that manually running ghostscript from the command line
against more or less any PDF file I have results in the same condition
of an indefinitely long run period. A search on google came up with many
very similar issues but they are all very old and supposedly already
resolved. However, I took my inspiration from these old problem reports
and tried inserting a -dNOTRANSPARENCY into the gs command line and
found that this causes gs to complete its processing in one to two
seconds and the resultant postscript output which I suppose would
normally in the next stage be passed off to foo2zjs for further
processing seems to be OK.

So to sum up, I can simulate the gs command from the command line,
inserting an extra -dNOTRANSPARENCY switch and this seems to work around
my problem with printing, but I cannot print from from any application
other than Libre Office as I do not know how to tell foomatic-rip to
pass this extra switch for me when it calls ghostscript (I guess this is
hard-coded?)

What I would like, (if my understanding is so far correct) is ultimately
a bug fix to ghostscript, and if this going to take a long time then
perhaps in the meantime you could supply me with a way to insert that
extra switch into the processing of my print jobs so I might perhaps
have a usable workaround in the meantime.

Thank you for your time and consideration of my problem.....
