A:Answer I haven't tried with this printer, but I've used photo quality paper in my previous Canon MX printers, using the paper trays. The normal paper trays pull the paper 180 degrees over a 2" roller, so card stock would not work well that way. This model has a rear (vertical) feed that I haven't tried, and that would pull the stock through a 75 degree bend, (rough guess). I would expect card stock to curl a bit from this feed path, along with the heat from printing. I use mine more for scanning and faxing, mostly I print on an old laserjet.
