A:Answer Hello Stormie. All options can be selected in the print settings dialogue box on your computer. First, create a custom 12" x 12" paper size, then under paper type, you can select the "Cardstock 1, 2, or 3" option depending on the thickness of your paper. For additional information, please see the User's Guide on our official Epson Support page. Regards, Kevin - The Epson Team.
