Printer List (Default) is empty

With the Print & Fax window open, point your mouse to the empty printer list then hold down Control and then click your mouse. The 'Reset printing system' dialog should appear. Select this and then restart your Mac. Now once restarted, open Print & Fax again and select to add. Select the printer from the default view or enter your network details and then see if the Print using menu has any models listed.

Did you use the '+' sign to add a printer yet. If you mean the "Default Printer" menu in Print & Fax Prefs, it seems that should be empty until you use AddPrinter ('+') to add your printer.
