It is a kernel problem, see
https://bugzilla.novell.com/show_bug.cgi?id=184825

Solution:
Don't use the CUPS "usb" backend for printing.
Use the HPLIP "hp" backend for printing.

None of the usual generic printer setup tools which I know about
is well prepared for HPLIP which works best when a print queue
is set up with its hp backend and where this backend is required
for a HP all-in-one device.
Therefore use the HPLIP setup tool "hp-setup" to set up the queue.


Kind Regards
