I use an Epson R2400 - Most of my prints are on (Arches) watercolor paper, which I further enhance with acrylic paint, after printing.   I've put everyting you can think of through this printer, from the thinnest almost tissue paper like fibers to posterboard. The size is limited to  max of 13X44, but if I need larger prints I go with on line service like http://finerworks.com/
