I have successfully changed the product name of our LaserWriter in
Glasgow so that it does not appear in the chooser.  Instead the name
used by lwsrv appears in the Chooser.  This is part of my scheme to
prevent unauthorised access to the LaserWriters.  The PostScript that
effects this is:

	%!
	serverdict begin 0 exitserver
	statusdict begin
	(F091.LocalTalk:LazerWriter) setprintername

where "LazerWriter" (with the 'z' instead of the 's') is the new product name.  
Remember to update your /etc/cap.printers file with:

	lwf091=F091.LocalTalk:LazerWriter@*

If you invoke lwsrv as

	lwsrv -n F091 -p lwf091 ...

then the name "F091" will appear instead of "F091.LocalTalk" in the
Chooser.  (atlook will however see both.)

You should send the PostScript using lwpr like so:

	$ lwpr -pF091.LocalTalk:LaserWriter@\* rename

where "rename" is the file containing the PostScript.  This has worked
for me since September.  In fact I managed to embed non-printable ASCII
in the product name like "LazerWriter^A^B^C" to make it more difficult
for would be hackers.
