LaserWriter IIf and IIg: No Automatic Emulation Switching



Does the LaserWriter IIf have auto-sensing for print emulation? The QMS
410 automatically senses HP PCL emulation, and switches the printer into HP
PCL emulation mode following a Postscript print job. Does the LaserWriter
IIf do this as well?

The LaserWriter IIf and IIg do NOT automatically sense, and change,
emulation modes. The QMS 410 provides auto-sensing for print emulation. In
other words, when you send it a print job, it determines what kind of job it
is and switched the printer into that mode. If you send it a PostScript job
it switches into PostScript mode. If you send it an HP PCL job it switches
into that mode.

The LaserWriter IIf and IIg do not do this. You set their ports up ahead of
time and whatever they are set up for it what they will accept. The trick thing
the LaserWriter IIf and IIg do is let you have more than one connection to the
printer (2 for the LaserWriter IIf, 3 for the LaserWriter IIg). Each connection
can be a different type of job. The only way to change emulations is via a
PostScript program or switch setting.

There is a big difference between auto-sensing and arbitration.
