That depends on what type of color laser and what paper. I've used an HP ColorLaser multi-function in my small office for the past 2 years and been very happy. For nice color prints, use glossy color laser paper, for standard prints and business docs you just use a laser paper instead of standard copy paper or multi-purpose.

Only problem with the HP's is the auto-document feeder. Has occasional problems grabbing, even after I put a new set of rollers in.
