I like to print things out because it makes them very concrete. I can literally see the whole code base I need to become familiar with. It's very useful for working in legacy code bases, or when trying to reverse engineer what is actually happening. The place memory (e.g. remembering that a variable was defined on the bottom of the third page of the printout) helps to situate you.

However, I'd say it's only worth it if you need to do "deep reading" of convoluted code, or if you're in very unfamiliar territory. Also, it doesn't work when the "printout" becomes too large—a full printout of a 30K LOC project is about 600+ pages. No way you're going to read all that!
