Do you ever print any of your code? I can't recall the last time I did it, and I know that it was never something that I did often. I'm not a real example, since I print about 2 pages a month on average (and even that I'm doing while muttering bitterly about dinosaurs).
I can see one good use for printouts, and that is for paper code review. I can see the value there, especially since red pen is one of the easiest ways to communicate. Although, I guess I would get stuff like this one all too often:
The only things that I print right now are object / tables diagrams, and even then, I don't refer to them, I'm using them as darts targets. (You wouldn't believe the amount of holes the Page class had during the time I did ASP.Net work).
