Description of problem: We've print queue points to a HP printer statically. Recently some print jobs can't be printed with error: D [09/Jan/2012:10:10:04 +0800] [Job 5189] prnt/backend/hp.c 768: ERROR: cannot open channel PRINT E [09/Jan/2012:10:10:04 +0800] PID 7439 (/usr/lib/cups/backend/hp) stopped with status 1! Then the print queue can't print anything although its status is idle: printer CUSIS_RES is idle. enabled since Mon 09 Jan 2012 10:18:17 AM HKT CUSIS_RES-5189 pscsprd 59392 Mon 09 Jan 2012 10:06:54 AM HKT I've to remove the print job and restart cupsd in order to make it accept print jobs again. There are some error reported in hpcheck (see below). Not sure if it's related. ----------------- hpcheck -r output ------------------- ]# hp-check -r warning: python-dbus not installed.

(In reply to comment #2) > # rpm -qi hplip > Version : 3.10.2 Vendor: Hewlett-Packard > Signature : (none) > Packager : samrat Well, this clearly shows that the package's origin is not Red Hat. This is what I got with Red Hat's hplip3-3.9.8: Version : 3.9.8 Vendor: Red Hat, Inc. Signature : DSA/SHA1, Wed 12 Jan 2011 03:40:58 PM CET, Key ID 5326810137017186 Packager : Red Hat, Inc. <http://bugzilla.redhat.com/bugzilla>
Thanks. Then I should uninstall the one we're using and install hplip3-3.9.8 from Red Hat instead?

The default printer error policy, i.e. what to do when a job fails, is "stop-printer" i.e. the queue becomes disabled. This will cause subsequent jobs to queue up until the queue is re-enabled. You can change this policy using system-config-printer (System -> Administration -> Printing). As for why it is that the job is failing: please use the "hp3" backend provided by the hplip3 package in Red Hat Enterprise Linux, and see if that makes any difference. You may need to uninstall the hplip package you got from HP before installing the Red Hat Enterprise Linux hplip3 package (although the Red Hat Enterprise Linux versions of hplip and hplip3 can be installed side-by-side). Switch that queue to the hplip3 backend using this command, as root: lpadmin -p CUSIS_RES -v hp3:/net/HP_LaserJet_P3010_Series?ip=192.168.12.181
Thanks. We don't have hplip installed. Btw, how to check the current backend being used? lpadmin -p CUSIS_RES -v hp3:/net/HP_LaserJet_P3010_Series?ip=192.168.12.181 Thanks a lot. /ST
(In comment #0 you mentioned having hplip-3.10.2-0 installed.) You can check the current backend being used using 'lpstat -s'. If the URI begins "hp3:" then you are using the backend from the hplip3 package, which is what we'd like to try.
Thanks. The URI returned by "lpstat -s" is same when I run "makeuri 192.168.12.181". I removed the 'unknown' hplip-3 rpm and installed hplip3 from RedHat. Still got some error when running hp3-check. Fyi also. Thx. ------------- cut here ------------- hp3-check[18656]: info: : Initializing. Please wait...
