Ive tried to setup my hp3420, the driver seems to be included in cups cvs, but if i try to add a printer in the web interface all i get is: "client-error-not-authorized" on the command line logged in as root: lpadmin -p printer -E -v usb:/dev/usb/lp0 -m deskjet.ppd lpadmin: add-printer (enable) failed: client-error-not-authorized Whats wrong?
