Would all those people who have blogs, or articles on their site, or share their thoughts with the world through their web pages please, please, please, please, please, please, please include a print stylesheet. Long articles that I'm either not in the mood to read right now, wish to keep, or are simply inconvenient to read at that exact moment (i.e. when I'm at work with someone is breathing down my neck) I like to print out, and getting your entire side column, header and everything else is not attractive, or useful.
It's easy, it's fast, anyone can do it. Check out the excellent Going to Print article by Eric Meyer over at A List Apart if you're not sure how to do it and make the web an easier place for those of us who wish to read it, just maybe not right now.
Thank you, that is all.
