I need a postscript program that can be loaded into a Laserwriter, and then
remains running on the LW.  The program should accept input from the RS-232 and
interpret it as Epson-like control codes.  I want my LW to emulate an Epson
printer, with of course some of the escapes implemented.

I cannot use one of the ascii -> PS convertors, because my application has to
print directly to a port, and the end-user cannot keep leaving the application
to close his redirection and run p2ps.

On a different note, is the any Apple specific Postscript command to change the
emulation mode of the LW ?  With DIP switches you can tell the LW to behave as
a LaserJet and this works well enough for me.  The DIP switches do not have the
life expectancy that I need for this job:  I have to switch between PS and LJ
several times per day, and the switches already feel <loose> to me.

So, I would like to run one PS program to switch from PS to LJ emulation.  Is
there any command to do this ?
