It's neither. No Dell inkjet printer will work with a Mac. no matter what driver you load. By the way, the printers are made by Lexmark to Dell's specs. They are not Lexmarks. The outside looks like Lexmark but the inside electronics are Dell.

Hey, I use a Mac too, and have the same printer. Have you found anything for this? I am losing hope. Please help if you can. There has to be a way around this.
