I tried to install a printer connected via AirPort, the printed is easily found and offered to "Download & Install", however, it failed with following dialog,
Setting up ‘Lexmark International Lexmark Optra E310…’
Can't install the software for the Lexmark International Lexmark Optra E310 because it is not currently available from the Software Update server.
Where can I find the driver?
Have you tried the Lexmark web site?
For OS X 10.8 or later:
