A:Answer Yes, it will print on card stock up to 110 pounds. If you're printing on stock heavier than 65 pounds, you'll probably find that you don't want to do duplex printing, because the results may not be satisfactory. You can still print both sides, but you'll need to do one side, flip the stock over, then print the other side. This is because the printer has to manipulate the stock to do duplex printing and the 110 pound stock may be too stiff for that to work properly.
