Oops, wanted everyone to know that the driver that Software Update downloaded and installed was 2.18, not 2.16 (which was the last one that worked for me). I just got done downloading the 2.18 driver directly from the Apple support website and installing it. Guess what? My printer is now working and everything is fine. If you are having issues, I suggest this route. Guess I solved my own problem, but hope this helps someone else.
