Can you do a complete system update and try again? If it still does not print, follow the instructions of the sections "USB printer", "CUPS error_log", and "Capturing print job data" on https://wiki.ubuntu.com/DebuggingPrintingProblems. Thanks.
Try also whether the command
sudo aa-complain cupsd
solves your problem. Run the command
sudo apt-get install apparmor-utils
if aa-complain is not installed.
