Bug Description

The filter hpps crashes (Python Traceback) on a broken pipe on stdout when the subsequent filter (the hp backend) errors out due to a network problem (see comment #8). As Linux distributions have automatic crash handling/reporting systems this causes annoying pop-ups which irritate the users giving the impression of a more severe problem.

To the HPLIP developers at HP: Please check all components for possible crashes in error situations.

Original report:

I have a HP Laserjet pro 200 color MFP M276n which was configured and working normally. I have it configured both directly with an USB connection, and through the network with a fixed IP.

Since a recent cups update (I believe), network printing does not work any more but the USB connection still works. When I try to print through the network I get a message telling me that the job has been send, and then I get a crash report. I don't know why apport is not intercepting the crash report, so I attach it manually here. In the "properties" window of the printer I see "Idle - Filter failed" and in the printer queue the job is "held".

The reason for the failure is:

D [22/Apr/2015:15:04:04 +0200] [Job 2639] prnt/backend/hp.c 824: ERROR: open device failed stat=12: hp:/net/printwalter?ip=10.60.16.199
D [22/Apr/2015:15:04:04 +0200] [Job 2639] PID 30723 (/usr/lib/cups/backend/hp) stopped with status 1.

Somehow HPs print backand is not able to communicate with the printer.

Please follow the instructions of the section "Network printer" on https://wiki.ubuntu.com/DebuggingPrintingProblems.

To the HPLIP developers at HP: Please make sure that nothing crashes or gives a Traceback if a network error (or some problem in another program), as we have a crash reporting system and so we get crash reports when the problem is somewhere else in reality and users get unneeded crash pop-ups.

See:

After further investigation, this issue turned out to be just a disconnected network cable. But of course the crash disconcerted the hell out of me.
