Round Robin Printing
On the Mac, it should be built-in but you have to use the CUPS web interface (or worse, the command line).
Make sure all the printers are defined first.
Then go to localhost:631 and define a new class that contains the printers of interest.
You may have to then define a new queue that contains that class (I forget).
