In addition to following the instructions of my previous comment, doe the following tests:
1. Run the following commands: cupsctl FileDevice=yes lpadmin -p test -E -v file:/dev/usb/lp0 -P /etc/cups/ppd/<name of your original print queue>.ppd Power-cycle your printer to reset the error from previous printing attempts and then print to the new "test" print queue. Are you able to print more than one job without power-cycling the printer now? 2. Another test is to blacklist the usblp kernel module. Run the command sudo echo "blacklist usblp" > /etc/modprobe.d/blacklist-usblp.conf sudo rmmod usblp Now power-cycle the printer to clean any previous errors. Check whether the usblp module is staying away: lsmod | grep usblp Print several jobs (into your original print queue, "test" from (1) will not work during this test) and see whether they are printing correctly without need of power-cycling inbetween. To restore your system after this test (and make "test" from (1) working again) run sudo rm /etc/modprobe.d/blacklist-usblp.conf and power-cycle your printer. Please do both tests, also if printing already works correctly with the first test. -- 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
