P2POutputStream: write error

Changing the driver to Generic Postscript sends a bunch of blank pages through the printer (some with garbage). But there is at least something going through.

:-Dustin

Changing the driver back to "HP Officejet 6300 series Foomatic/hpijs, hpijs 2.8.7" yields the P2P error again.

Changing the driver to "HP OfficeJet 6110 - CUPS+Gutenprint v5.2.0-beta4" gets me printing again.

More debugging output...

It seems that CUPS does not set the TMPDIR variable any more. Lars, can you add to foomatic-rip that it sets TMPDIR to /tmp when TMPDIR is not a writable directory and also uses /tmp then? In reality it is a CUPS bug, but we should allow the use of foomatic-rip also with these versions.

Seems that CUPS is not setting TMPDIR any more. Will report it upstream.

Problem reported to CUPS upstream:

http://www.cups.org/str.php?L2962

Fixed upstream (in foomatic-filters).

Uploaded upstream fix: foomatic-filters_4.0.0~bzr174-0ubuntu1

Dustin Kirkland, before you update to the fixed foomatic-rip, can you try to print again and see if any messages with "audit" appear in /var/log/syslog or /var/log/messages? Thanks.

After some discussion on IRC it turned out that Dustin Kirkland has linked /tmp to /dev/shm (shared memory, something like a RAM disk). AppArmor is blocking the access to /dev/shm as it is not explicitly allowed in /etc/apparmor.d/usr.sbin.cupsd (See below). So there is no bug in upstream CUPS or in our AppArmor configuration.

The new foomatic-rip works around the problem by trying several temporary file locations. Especially it starts with CUPS' own temporary file directory, usually

/var/spool/cups/tmp

So you either need to install the new foomatic-filters package or edit your /etc/apparmor.d/usr.sbin.cupsd giving the same permissions to /dev/shm as to /tmp.

Closing CUPS task.

Perfect, thanks Till for your hard work.

I have tested the updated packages and verified the fix.

Thanks!

Men, if you have another driver for your device try it, i have a HP Larserjet p1005, and when i print with hpijs driver only i get numbers with the top saying it's "pdf-1.3 pdftopdf", so i change the driver to foomatic/foo2xqx and the hpijs to foomatic/hpijs-ZJS now i can print without that error, that error was only with "hpijs", so i get now the foo2xqx that's normal quality, and hpijs-ZJS draft quality.

greetings
