hal-cups-utils did not read the device IDs of the printers correctly. I have fixed this now.
Please replace your file
/usr/lib/hal/scripts/hal_lpadmin
by the attached file and make it executable with
sudo chmod 755 /usr/lib/hal/scripts/hal_lpadmin
Then unplug and replug your printer. Does it get re-enabled now?
