Ran into this problem today while trying to print to my networked printer, an HP Officejet Pro 8500. The system is up to date, has Firefox 27. Tried printing twice, using this hp-doctor command and a reboot in between attempts, and now have 2 jobs stalled in the queue. Here's what I see. /var/log/syslog: Feb 11 11:32:36 diamond anacron[1147]: Job `cron.daily' started Feb 11 11:32:36 diamond anacron[2135]: Updated timestamp for job `cron.daily' to 2014-02-11 Feb 11 11:34:19 diamond whoopsie[1331]: online Feb 11 11:35:20 whoopsie[1331]: last message repeated 2 times Feb 11 11:52:48 diamond kernel: [ 1530.398251] audit_printk_skb: 84 callbacks su ppressed Feb 11 11:52:48 diamond kernel: [ 1530.398256] type=1400 audit(1392141168.213:47): apparmor="STATUS" operation="profile_replace" parent=2448 profile="unconfined" name="/usr/lib/cups/backend/cups-pdf" pid=2452 comm="apparmor_parser" Feb 11 11:52:48 diamond kernel: [ 1530.398265] type=1400 audit(1392141168.213:48): apparmor="STATUS" operation="profile_replace" parent=2448 profile="unconfined" name="/usr/sbin/cupsd" pid=2452 comm="apparmor_parser" Feb 11 11:52:48 diamond kernel: [ 1530.399037] type=1400 audit(1392141168.213:49): apparmor="STATUS" operation="profile_replace" parent=2448 profile="unconfined" name="/usr/sbin/cupsd" pid=2452 comm="apparmor_parser" Feb 11 11:53:32 diamond anacron[1147]: Job `cron.daily' terminated (exit status: 1) (mailing output) Feb 11 11:53:32 diamond anacron[1147]: Can't find sendmail at /usr/sbin/sendmail, not mailing output Feb 11 11:53:32 diamond anacron[1147]: Job `cron.weekly' started Feb 11 11:53:32 diamond anacron[2569]: Updated timestamp for job `cron.weekly' to 2014-02-11 Feb 11 11:53:34 diamond anacron[1147]: Job `cron.weekly' terminated Feb 11 11:53:34 diamond anacron[1147]: Normal exit (2 jobs run) Feb 11 12:17:01 diamond CRON[2719]: (root) CMD ( cd / && run-parts --report /etc/cron.hourly) Feb 11 12:37:47 diamond dbus[850]: [system] Activating service name='org.debian.apt' (using servicehelper) Feb 11 12:37:48 diamond AptDaemon: INFO: Initializing daemon Feb 11 12:37:48 diamond dbus[850]: [system] Successfully activated service 'org.debian.apt' ...
