Hi!

I happen to have a SilentWriter LC 890 which is a full postscript laser
printer made by NEC. Besides full postscript (batch & interactive) it offers
a fairly good Hp LaserJet & Diablo emulation.

A little control pannel lets the user set the machine's state (including emula-
tion mode) but I would like to be able to select the mode from software.

I have managed to write a postscript 'program' that puts the printer in HP mode

----------
	executive			* To put the printer in postscript
					  interactive
	serverdict begin 0 exitserver   * So that the settings I do will last
					  for more than 1 job

	executive			* since the precedent line ended the
					  current job and restarted me in
					  postscript batch
	statusdict begin		* so that I have access to the system's
					  status variable
	5 setsoftwareiomode		* into HP mode
	end				* Voila, I'm in HP
----------

Now I really don't know how to do the other half of the job!

Is there a way from HP or Diablo emulation mode to 'escape' into postscript so
that I can change the mode back???

As a side issue, the first part of my postscript program/script sets up the
system so that I can make permanent changes to the settings. Once I have set the
mode to whatever I wanted,  how do I tell it to 'put the write protect back
on' ???

Thanks in advance, merci!

PS:	I *did* RTFM and it's not there!
