Here is a tip on how to get a LaserWriter IINT working with a Sun 360 system
under UNIX.
The problem most often described is that the Sun provides PostScript to the
LaserWriter, which begins imaging the job (green light flashing) but nothing
further happens.
The cause of the problem is probably that the UNIX spooler was adding a header
to the print job. After toggling the option off, the LaserWriter IINT should
work as expected.
