I can see this is useful, but a bit of a hack.
To the posters saying printing is obsolete. Printing is not becoming any less popular:
When tablets become commonplace with much higher resolutions, viewing angles are much better, contrast ratios too, then displays will dominate paper. Display dot pitch is extremely slow to improve, not much different from 10 years ago, and 6 or more times that of print. As of today printing has a lot of advantages over screen or e-book reading.
