Hi All, After installing Leopard 10.5 I noticed that I was having problems printing from my C5200n OkiData printer. I contacted OkiData Support by email, within 2 days they emailed me back with a beta driver for the C5200n and it worked perfectly. So the solution is to email them from their support portion of OkiData website and they will cure your problem until the drivers are posted for the public.

This is a pointer in a potentially right direction. This is not a well researched solution to your issue.

Understanding that MAC OS X is "BSD-like" under the covers this link with considerable research may yield some results however the solution is not likely to be very "MAC-like" installation.
