My Mac at work is connected to a Lexmark Optra S 2450, to which I can print from Word and Lotus Notes but not from any Adobe program. Not even a few text characters from ID, or a simple scribble from Photoshop. I have been to the Lexmark website to try and find a driver, but I couldn't even find that model Lexmark listed, much less find a driver. Does anyone have any experience successfully printing to a Lexmark from a Mac (G5 with OS 10.3.9)? If so, what driver do you use? Was there any special trick to getting it to work?
