Looking for 2 tray office printer/scanner

Hello,
My boss wants a new laser printer. It has to have 2 paper trays - one to hold blank paper and one to hold letterhead. He wants the ability to choose which tray to print to right from his pc, not from the actual printer where he would have to physically get up and push a paper selection button. He also would like the ability to print in color.
He prints quite a bit, so it definately has to be for business use as opposed to personal
Does anyone have any suggestions?
