Can you clone the print queue with which you got the segfault of the usb backend with commands like
cupsctl FileDevice=yes lpadmin -p test -E -v file:/tmp/printout -P /etc/cups/ppd/<name of original queue>.ppd Now send the print job which caused the segfault to the queue "test". After that find the device URI of your original print queue with "lpstat -v") and run sudo -s apt-get install cups-dbg ulimit -c unlimited DEVICE_URI=<device URI of the original print queue> /usr/lib/cups/backend-available/usb 1 1 1 1 '' < /tmp/printout If the USB backend crashes, you get a file named core. Run gdb -c core /usr/lib/cups/backend-available/usb and when you get a prompt, run bt and post the output here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/887094 Title: usb printer backend crashes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/887094/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
