Wow. Are you sure? This is certainly not the case with my LaserWriter
II NTX (Version 47.0). I can appreciate that I don't have the newest or most
wonderful LaserWriter, but I'd be surprised if recognition of %! were built
into the printer itself. Are you sure it's not the print spooler that's
recognizing %! and filtering it to text (lpr) mode? If you're running
TranScript, TranScript does indeed do this at the spooling level.
