You can try to get a backtrace as follows: Make sure you have the package cups-db installed and it matches the version of your installed cups package.
Run the following commands in a terminal window: sudo -s ulimit -c unlimited cat <large plain text file> | DEVICE_URI='usb://HP/LaserJet%206MP' /usr/lib/cups/backend/usb 1 1 1 1 '' If you get a segmentation fault or any other crash saying "core dumped", run gdb -c core /usr/lib/cups/backend/usb As soon as you get the prompt inside dbg, run backtrace full and paste the output here.
