I print code from time to time, when I have to modify an existing project I never read before. Perhaps 5 or 10 pages only. I like to make annotations with a pen, or cross irrelevant parts. I usually use an editor to try to make sensible page jumps first, and in an extreme case I used adhesive paper tape to make a looooong page and then help to refactor the code.
