Not being an expert on the Mac, I do have an idea that might get around this
problem.  I believe when the Mac tries to print to the laserwriter, it first
checks to see if the laserprep file has been downloaded.  If not, it will 
download the laserprep file.  If somehow the laserprep file could be fixed up
so that it printed the required legend on each page, then you would be OK as
long as you have control of the laserprep file.  This could be accomplished
by putting a hard disk on each Mac with the application and the laserprep file,
or putting it onto all of the application floppy disks.  Of course, if someone
learned how it was done, they could change the laserprep and then power cycle
the printer.  If that Mac were the next to print, then the "watermark" would
disappear.

I don't know how you would do this, but you might be able to use some other
machine as a print server on appletalk and connect the printer to it.  Then
all the printing would pass through that machine and you would have some more
control of what was in the printer.  You might be able to accomplish this with
a cheapie PC with an appletalk card and the printer on a serial port.  You might
also be able to do it with a Mac the same way.
