QTR-Quadtone RIP

Hello All
I have two 2200s I'd like to hook up to the same
computer and drive both with QTR. I can't seem to make
it work. I am on a Mac, newest system, newest QTR. The
printer setup utility will only set up one QTR
printer. I tried to name the printers differently, but
that didn't work. 
So does anybody know 1.) Can this be done? 2.) How to
do it.
I searched the archives and could not find any hints.
Thanks in advance for any insight.
