[Pkg-cups-devel] Bug#658579: cups: parallel device gets stuck at 100% CPU with Xerox Phaser 3121

[Shai Berger]

Package: cups
Version: 1.5.0-16
Severity: normal

Dear Maintainer,

First of all, I would like to apologize if this is not the right
package; I think it is, but I'm really not sure. Maybe something
in the kernel.

In the last 2-3 days, it seems every operation that tries to access
my Xerox Phaser 3121 printer, which is connected through the parallel
port, gets stuck and never completes; I get a process on the host
that looks like this in "ps axuww":


lp        9324 99.9  0.0   5732  1104 ?        R    07:57 268:48 parallel:/dev/lp0 1547 sigal Cooks 1 TonerDensity=3 Duplex=None number-up=2 number-up-layout=btlr PageSize=A4 Resolution=300dpi InputSlot=Auto EconoMode=0 noJamRecovery Altitude=LOW MediaType=OFF PowerSave=5 job-uuid=urn:uuid:d8331db0-edd9-3d65-72d5-81b8567a00e8 job-originating-host-name=localhost time-at-creation=1328334501 time-at-processing=1328335027

The only way I found to solve this is to "lprm" the print jobs, bring
down the cups service, and "sudo kill -9" the process. If I just bring
down cups, the process stays up (also does not respond to SIGTERM); if
I just kill the process, cups respawns it; if I just bring down cups
and the process (leaving jobs in the queue), cups restarts it as soon
as it is brought back up.

Some of the time -- can't be sure -- I've gotten error messages printed
by the printer, complaining about a timeout.

Until yesterday, I was using the older, Samsung ML-1710 driver from
Foomatic/gdi; I switched to Splix with the actual Xerox model, but
it made no difference.

Another printer, connected via USB, continues to function normally.

Thanks for all your good work,

Shai.
