Well… let me know… : )
Hi @areva
Long story short, we don’t recommend or encourage printing out the book. The book is filled with lots of examples with sound synchronized to explanations of what is going on in the music and that would all be lost in a printed copy. You’d be a reading a lot of “listen to this!” but there’d be nothing to listen to.
That said, if you get the web version I don’t think there’s anything stopping you from hitting the print button on your browser 
Just be aware that you’ll be missing a lot of what makes the book special.
