Paper is dead. Surely you got the IM/email/tweet?
It's amazing how often people need reminded of that. I just got wrapped up in a discussion about how hard it might possibly be for some not-so-savvy people to print from their browser and that we should create a PDF version of some web pages so that our customers can easily print. Seriously?! I'm all for serving my customers, but that's borderline insanity.
How about a simple icon and a Javascript window.print() call?
