Next testing round: cups 1.5.3-0ubuntu2~ppa7 is uploaded to my PPA now and this respects uni-directional devices and gives some more messages in error_log.
Please repeat the tests with it (with and without blacklisting usblp) and attach syslog and error_log of the failing tests. In addition, you can try to force uni-directional mode by lpadmin -p <queue> -o usb-unidir-default=true and restore to normal mode via lpadmin -p <queue> -o usb-unidir-default=false For <queue> the name of your print queue has to be inserted. Please repeat your tests with forced uni-directional mode. -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
