I'm able to easily print from my computer. The problem si I cannot get the scanner to work at all. Any suggestions??

I've had the same problem with my HP printer. The resolution was to remove the printer from CUPS and reinstall it using the hp:/ URI. It should be someplace in the list of possible devices. With the usb:/ URI, CUPS printed perfectly but the HPLIP toolbox didn't detect the device. With the hp:/ URI, however, HPLIP picked it up with no problem.
