Parallel printing not supported on 12.04LTS

Question

I upgraded to Ubuntu 12.04 and now CUPS printing cannot find my printer. It's an HP 970cse and uses parallel printing. Isn't parallel printing supported anymore?

Answer 1

Please make sure the lp, ppdev, and parport_pc kernel modules are loaded, open a terminal and run the following commands:

sudo modprobe lp
sudo modprobe ppdev
sudo modprobe parport_pc
