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!

Send ESC, DEL, zero (thats \033\0177\060) in the other modes to get back to postscript. I'm not sure if you have to wait until the job is done printing or not. You will lose downloaded HP fonts when you switch back to postscript even if they were loaded "permanently". I called the NEC information number listed in the printer manua to get this. Les Mikesell

The sequence you are looking for is "ESC-DEL-0" (ASCII Escape, Delete, Zero) from the HP or the Diablo emulations. This should be followed after a second or two delay by a CTRL-D (ASCII EOT). This will return to the PostScript batch mode (mode 0). >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.

It is sufficient to use: statusdict begin <MODE> setsoftwareiomode end followed by a short delay and a CTRL-D (EOT). Note that when changing between emulation modes, the CTRL-D is required before the new mode becomes effective. When you *do* need to use exitserver to permanently set data, the magic CTRL-D (PostScript end-of-job indicator) will return you to the PostScript server (the "protected" mode as you call it).

We are running Unix System V and have the printer connected through the lp scheduler. The interface file that we have is designed to run jobs to the laserjet emulation (which is our default setting). Sending the option '-opostscript' to 'lp', we set it up into postscript mode and can then dump postscript programs to the printer. Here is the stuff that you will find relevant (I hope): To run a postscript batch job (starting in HP Laserjet emulation): echo "\033\0177\c" echo "0end" echo "Wait 2" echo "\004\c" sleep 10 echo "statusdict begin" echo "5 setsoftwareiomode" echo "end" ... send postscript file to the printer ... echo "\004\c" The first bit takes the (pseudo-) HP Laserjet printer into postscript mode, signals end-of-job, and then it sets the job back to HP Laserjet mode. As documented in the manual, this change doesn't take place until the end of the current job. There are some problems with this in that HP Laserjet jobs and Postscript jobs cannot be intermixed well without occasionally leaving the printer in postscript batch mode.

To return from HP emulation to PostScript, use the 3-character sequence: <ESC><DEL>0 This is NOT in any of the NEC LC-890 documentation. I found this while skimming documentation for a Ricoh PostScript printer which also has an HP emulation mode. I've tested it on the LC-890, and it works fine. No, I don't know what the equivalent command is for getting out of Diablo 630 mode, but I'd like to find out! By the way, if my memory is correct, you don't need to invoke exitserver to use the setsoftwareiomode operator.

Does anyone know if this or some other method of escaping HP Emulation will work on the Apple LAserWriter IINTX. Here again a method to escape Diablo an any of the Apple LaserWriters could be very useful as well. ADVthanksANCE
