Xerox has unbelievably awesome driver support.  My 6600dn (which is no longer made), gets regular driver updates.  Supports "10.5 or below" on up through 10.10.

I'm a HUGE fan of Xerox.  Plus, it's a real PostScript printer.  I can even print to it from my System 7 machine using the Laserwriter or PostScript Printer driver.
