I assume you are already a member of "lpadmin" group, right?

If so, re-check CUPS settings ("/etc/cups/*.conf") and try again.

To run GUI based applications from root, try better with "gksu hp-setup".

Nope, computer just tells you how it feels but you need to interpret its

ready-to-use and easier to deal with ;-)
