A:Answer Yes it does. You have to use the rear document feeder on the WF7720. Also, as you might imagine, it uses a lot of ink at that size. If you're doing much printing, you'll want to buy the xl cartridges. Save your pennies. I've included the links to the black, magenta and cyan cartridges below (couldn't find the yellow). They sell a 4 pack, too; $124.96.
The print quality is nice. I had to play around with print settings on the driver. See the pic of me with a print of my digital artwork.
