Yep.  We've changed the type on our Laserwriter a year and a half ago, and 
we have had no unwanted printing since.  I've modified the Laserwriter 
driver to lookup the different type, and given it to those allowed to 
print on our printer, and it works just fine.

The code to change the Laserwriter's type is the following (download using 
SendPS from a Mac, or tlw from a Sun, or whatever your favorite PostScript 
downloader is):

serverdict begin 0 exitserver % assuming your printer password is 0
statusdict begin
(PrinterName:PrinterType@*) setprintername % default PrinterType = LaserWriter

The modifications that need to be done to the Laserwriter 5.2 driver to 
see the new printer type are the following (change the string "LaserWriter"
to whatever your new type is):

Required:  STR -4095, STR -4096, PAPA -8192, insc 0
Optional:  STR -4082, STR -4086, STR -4091, STR -4094, STR -8160
           PREC 109, LWRR 0, and all the DITL's containing "LaserWriter"

Note:  The Optional changes just make alerts and dialog boxes have the 
       correct type of printer in their messages; if you don't mind it
       still being called a LaserWriter in those boxes, then the optionals
       don't need to be changed.

Finally, change the name of the modified LaserWriter driver itself to be
the same as the type of the printer.

Hope this helps.
