I just picked up a Konica Minolta PagePro 1350W laser printer on sale cheap (for $50!), only to find out it was not compatible with OS X Tiger, and I could not find much help searching on the web.
However, I found a related hint for unsupported printers and Foomatic. So I used the Foomatic install linked from that hint, and this PPD from linuxprinting, and voila, printing on the cheap!
