I have exactly the same printer. It is important that you are in both 
the *lp* and *scanner* groups to use the device.

For administrative purposes, I believe, it is necessary to be in the 
*sys* group.

Did you also check the sane configuration file to ensure the *hpaio* 
backend is enabled? I think it is in /etc/sane.d/dll.conf
