[comp.laser-printers] Adding multi paper-tray support to Macintosh laserwriter driver

herm@polari.UUCP (03/21/91)

I am planning to attach my Apple Macintosh to a 3rd party postscript 
printer which has multiple paper trays.  I would like to use the standard 
Apple laserwriter driver (or slightly modified version thereof)
and be able to specify which paper tray to use from one of its dialogs 
("page setup" or "print") .  
Is such a modified version of the Apple laserwriter driver already available? 
If not, is it possible to add hooks into the their laserwriter driver so 
that I can modify  one of its dialogs by adding a button or two, 
and writing my own "hook" routines which would respond to these new 
button inputs? I can then generate the postscript commands to do a tray 
select.
