Yeah, Xanté or the Okidata printer is really good for that kind of stuff. In fact, when I was running a small print shop that's how we broke into the digital market. Tested the waters with a Xanté. Now they are running 3 full sized digital copiers along with the presses. But if it hadn't been for the Xanté they might have missed the digital market all together.
Using a desktop inkjet is not the way to go about it... seriously. Been there done that. You'll never match profiles, and stuff will never look like the stuff you outsource. Plus, ink cost is rediculous... unless you are dedicated to full on CIS. But then you are tied into specialty papers, that aren't really professional to hand out to people. No one want's an inkjet business card. You can get away with it for photographs, or menus that you are going to laminate.
