We have the BizHub C350 and whilst we can print from the OS 10.4 machines and any software, including Quark 6.52 (which we have, though we no longer use) we can't print to it from anything under OS 10.5.
That's one of the reason's we've downgraded the new 10.5 machines to 10.4.
What OS are you using? Have you got the latest PPD? Minolta, for us, have been incredibly unhelpful.
