Public bug reported:

This bug results in one blank page being produced while printing Adobe
DRM file using cups-pdf printer (see also post #24 in Bug #782309).

"Your problem is caused by cups-pdf. So please file a new bug on cups-pdf (and 
attach this error_log also there).

First, the Ghostscript called by the cups-pdf backend errors out, but
the backend is closed without error exit code, making CUPAS assuming
that the job got correctly printed. This one can see here in the
error_log:

D [19/Sep/2011:22:24:44 -0600] [Job 61] GPL Ghostscript 9.01: Unrecoverable 
error, exit code 1
D [19/Sep/2011:22:24:44 -0600] PID 23327 (/usr/lib/cups/backend/cups-pdf) 
exited with no errors.
D [19/Sep/2011:22:24:44 -0600] cupsdMarkDirty(-----S)
I [19/Sep/2011:22:24:44 -0600] [Job 61] Job completed.

Second, the cups-pdf saves a PDF file consisting of one blank page. In
this case where Ghostscript has errored out it should not write a file
at all.

Third, and this is the most important, Ghostscript refuses to turn Adobe
Reader's PostScript into PDF if the original PDF was encrypted (had DRM
settings). This measure is done to prevent from simply stripping off the
DRM settings."

Thanks,
