After much research, I located only one multifunction color printer model that meets all of my specifications, the HP LaserJet 2840. However, I have rarely seen a product with so many negative user reviews, particularly from Mac users, who report that HP's Mac drivers are buggy and incomplete. (Windows users complain about the drivers too). Nearly everyone also complains that it is excessively noisy.
Does anyone have any experience with the LaserJet 2840? Is anyone aware of alternatives?
