Hm... Digitally simulating the effect of a traditional work of art lying around your studio when it's in progress might not require printing, if you spend a lot of time on the computer when not drawing.
You could keep screenshots of your WIPs as your desktop background. Or put them in a Sticky Note or Transparent Collage that opens when you log in. You can even make them sit over of your other windows if you don't mind the intrusion.
