I am currently reading "Mindstorms," by Seymour Papert, which is the namesake of the LEGO product for building intermediate robotics. The concepts of that product and its language—LEGO/LOGO—are inspired by Mr. Papert's work therein. Read it. Let's compare notes afterward, because I'm afraid that your questions betray your all-too-easy view of "education." To the questions:
Reduce the size by half and arrange the pages side-by-side and print duplex. It doesn't take much paper, the batteries never run out, and it is more portable (in the case of up to a few books).
If you live in the West, ask your local library what book binding equipment they have. Often, libraries bind books since the covers wear down over the years. If you can get your book bound, the result is, well, like a library book! Some countries even have shops that will do this for you for a few US dollars per book. Here in Thailand, getting eBooks printed is one of my favorite activities.
(Shameless plug!) Recently, to teach myself Rails, I made a site (from 100% free software) offering convenient eBook printing and delivery: Siam eBook Printers. We discount books about open source too. It doesn't make much money, but it was possibly the most fun project I've ever done. Contact me if you want to know how it works!
