Our network manager, Professor David Jeffrey, writes in reply:

Certain features of a postscript printer can only be changed after
you quote a password. Thus if I send the following postscript file
to a laser printer, it spits out a sheet of paper with the
obvious message printed on it:

100 100 moveto
(This message will print and the page will be ejected) show
showpage

Now, however, suppose I want to change the baud rate on the serial
connection, or permanently download the fonts used by my word
processing package. I first must quote the password.
If I send

25 9600 2 setsccbatch

then nothing will happen. If I send

serverdict begin 0 exitserver
statusdict begin
25 9600 2 sccbatch

then voila! the printer is now using a 25-pin connection at 9600 baud.
The 0 in the above is the password. If I want to change it I execute

oldpassword newpassword setpassword

If the old password is 0, then any program can change it for you.

Rob Corless speaking again. 

In the context of the Macintosh, what happens is that after I have
physically moved the printer down to my office (the Mac Vaps haven't
been installed in the network - novell netware - yet) and hook it
up and Choose it, I then try to print my Microsoft Word document.
It tries to do it, but the PrintMonitor flashes at me.  Looking at
the PrintMonitor I try again and this time see a message that
includes the words "incorrect password".  So setting the password
affects the start of a print job somehow.  I would like to be
able to make my driver know what the password is.  If I knew where
to find the 
serverdict begin 0 exitserver
command I could change the zero to what I need.  But, I don't
know where this is kept.  I expect that I will have to use RezEdit
but the hard part there is knowing where to look.
