Can anyone recommend a color laser printer that: 1. prints well on card stock and 2. prints well on both sides of a sheet of card stock -- duplex printing not required. I am a designer and when creating prototypes I often have to print on 2 sides of a sheet of card stock and because it's an illustration I don't bother with duplex printing. I used to have a Konica Minolta Magicolor 2300DL that was AMAZING but died. Just replaced it with a Konica Minolta Magicolor 7450EN and it's HORRIBLE. It doesn't play nice with my mac and the print quality is awful on the 2nd side. Not to mention the pages never seem to go through perfectly straight. It's been a nightmare. Any advice/suggestions are most welcome. I'd prefer a stand alone printer -- no scanning required. THANKS!
