I have a sample parallel printer (Epson Stylus Color 880) with USB->Parallel Adapter now and can reproduce the bug. After a few jobs, sometimes already during the first job) the printer gets unresponsive (USB timeout in error_log) and no device ID returned when canceling the job and running "sudo /usr/lib/cups/backend/usb". I have to cancel the job and to power-cycle the printer to continue printing.
I tested this with usblp blacklisted and without forcing uni-directional mode. More tests to follow. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/987485 Title: Can only print once with USB to parallel adapter and HP 4L To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/987485/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
