2) Select Printers
3) Click 'Click here to add a new printer)

Additional Information:
* This does occur on openSUSE Aeon; the built in printer settings work as expected.
* Currently this can be worked around by navigating to https://localhost:631 and adding a printer through the CUPS interface, logging in as the root user when prompted. This implies that it is a permissions issue.
* This bug also occurs in openSUSE Tumbleweed.
