I have an HP Officejet 5610v USB connected to a Toshiba Satellite L305D-S5934 with Ubuntu 9.10 and I also have the same problem. I try to power cycle the printer, disconnect then reconnect the USB cable, and click System -> Administration -> Printing -> right click the printer icon and check Enabled. The only thing that recovers this is to restart the laptop, but if after I do so I disconnect then reconnect the USB cable, then I would have to restart the laptop again.
It may be due to a problem with system-config-printer-udev: apt-cache policy system-config-printer-udev system-config-printer-udev: Installed: 1.1.12+git20090826-0ubuntu8 Candidate: 1.1.12+git20090826-0ubuntu8 Version table: *** 1.1.12+git20090826-0ubuntu8 0 500 http://us.archive.ubuntu.com karmic/main Packages 100 /var/lib/dpkg/status The solution would most likely be to upgrade to Ubuntu 10.04 which contains the newest version of system-config-printer-udev. -- HP Printer Deskjet F4100 series not working after updating from 9.04 to 9.10 https://bugs.launchpad.net/bugs/476508 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
