After multiple calls to Apple (results were "Duh?") I managed to get to a very intelligent and helpful Xerox technician. He used Macs, and to make a long story short - remembered this problem from NeXt days - seems that Apple just used the old NeXt print code. This code messed with the printer "white point".
At any rate - Xerox created and sent me a new rom for the printer overnight that fixed the problem. If any of you have this problem, just let Xerox know and they'll take prompt care of it.
