I am using an 030 board to drive a NextPrinter under 2.1, but have been unable to do this under 3.0. The headless 030 boots fine but panics when it tries to start WindowServer. Everything else works fine, but WindowServer is needed to run the printer :-( Has anyone succeeded in getting a headless Next to print under 3.0? ...
