I have re-posted this from comp.sys.mac.
I have two short questions. Can anyone help?
1) How can someone print to a postscript file in Microsoft Word?
(there is a way in Matlab and in MacWrite but Microsoft was
unable to tell me how to do it in Word, though the support
staff was convinced you could do it).
2) How do you change the printer password sent to your laser printer
from a Macintosh?
I'll give some context for the last question so people can perhaps
help with the real problem. It recently came to the attention of
our network manager that there was a worm/virus/trojan horse around
that screwed up laser printers by changing the password for the
Postscript engine. The password defaults to 0 and the virus relies
on this. So, we changed the password.
Our IBM printing software we have adjusted to this change. No-one
here knows how to adjust the Macintosh software to allow us to send
the new password to the printer so our files will print. Since the
laser driver is a centralized construction, this ought to be easy
to do, provided you know where to look, which we don't.
I would greatly appreciate any help from any readers.

The file <info-mac>tips>generating-postscript.txt has been passed on to me. Thank you very much for doing so. I will attempt to print on our printer now by manually inserting the password change into the generated files. If I have to keep doing this this will cause me some pain, however. Does anyone have suggestions for curing this problem permanently? -- ======== Robert Corless, Applied Mathematics, University of Western Ontario ======== London, Ontario, Canada N6A 5B9 e-mail : RCORLESS@uwovax.uwo.ca

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. -- ======== Robert Corless, Applied Mathematics, University of Western Ontario ======== London, Ontario, Canada N6A 5B9 e-mail : RCORLESS@uwovax.uwo.ca

Two people responded helpfully to my query about finding "the" place to change the password for the LaserWriter. I am posting their responses and a summary of my progress so far.

Chaz Larson (clarson@ux.acs.umn.edu) writes: >Within the "LaserWriter" file, you will find the above command in >STR# ID = -4093 >Hope this helps. This string is indeed there, and I changed the 0 there to our new password. However, this didn't help. I still got the Error: password incorrect: OffendingCommand: exitserver message from the printer. So I looked a bit further and found "exitserver" in 3 more places in the LaserWriter file: in POST -8161 "exitserver" is part of the definition of a PostScript word ExitServer, whose purpose I am unable to fathom. The sequence serverdict begin exitserver, without a 0 between the begin and exitserver, occurs in ExitServer. I made no changes here. In POST -8192 there is a sequence serverdict begin 0 exitserver, which apparently is what is issued after a printer error in the case of a restart. I changed the 0 here to our password. In PREC -109 the operator "exitserver" appears in what is apparently a message that is issued after a printer error. I made no changes here. I found no other occurrences of "exitserver". Unfortunately, it still doesn't work. I still get the error message. I checked via the IBM machines that I do indeed know the correct password. I suspect I have missed finding the crucial place - perhaps in LaserPrep? It may be hardwired in somewhere, or it may be that word ExitServer needs to be modified. Can anyone help? In the meantime, I am working around it by using Xtalk from an IBM to set the password back to 0 and then trundling the printer down here to use. This of course leaves the printer vulnerable while I am using it, and I have to set the password back when I take it back. -- ======== Robert Corless, Applied Mathematics, University of Western Ontario ======== London, Ontario, Canada N6A 5B9 e-mail : RCORLESS@uwovax.uwo.ca
