I'm having the same problem ("40 EIO 1 Bad Transmission" - "Press Go to Continue") - using JetDirect like above. It prints fine and resets the error after the print job. My /var/log/cups/error_log is empty, but syslog is logging a string of these:
Aug 23 18:43:37 psyserveftp HP_LaserJet_4050_Series?ip=192.168.1.99: prnt/backend/hp.c 496: unable to connect hpssd socket 2207: Connection refused Aug 23 18:45:00 psyserveftp last message repeated 2 times After turning on debugging my error_log is showing (Not sure if relevent): Discarding unused printer-state-changed event. Discarding unused job-progress event. The whole debugging error_log is attached along with my dmesg is needed. ** Attachment added: "/var/log/cups/error_log" http://launchpadlibrarian.net/17041904/error_log -- Error while printing with HP Laserjet: 40 EIO Transmission Error https://bugs.launchpad.net/bugs/229981 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
