Generally, I prefer the screen, unless i'm inside a really large loop. For example, I interited a program that has a nested if statement that is several hundred lines of code. I've printed that out and refer to it when dealing with that program (which of course, I am rewriting because it can be done much simpler).

If you give a man a fish he will eat for a day.
If you teach a man to fish he will buy an ugly hat.
If you talk about fish to a starving man, you're a consultant.
