uh, I happen to have a Personal Laserwriter NT, configured as a serial printer,
9600bd,8,N,1, XON/XOFF, binary postscript, so I know it works.  In fact, that
is one of the default settings for this printer.  It shows how to set it up
(more or less) in the appendices of the printer manual.

BTW - There is no such thing as a parallel port on a PLW NT...
