The QMS PS-410 automatically senses if the print job is PostScript, HP PCL,
or HP-GL.  One of the ways (but not the only way) that it senses a PostScript
print job is if the print job begins with a %!.  As this auto-sensing
ability will become more common in the future we should all now begin our
PostScript files with %!, even if it isn't an EPS file.
