There is a huge difference in digital printing or offset printing. The quality of a offset printed book is so much better then a digital printed book, especially if there are a lot of photos in it. Same goes for a glued or a really binded book. The higher quality, the higher the price.

The e-books most of the time touch one or two subjects or techniques and in printed books you will find more and different techniques. But the e-book tutorials go in to depth a lot more.

There are so many differences, you can not compare those two different medias. My conclusion is that although I like quality printed book way better then electronic books, it is not possible for a reasonable price to print every tutorial in a high quality.
