Printer Friendly

How many web sites have you been to that don't offer a printer friendly version and/or don't print nicely? I've been to MANY. Today I came across this website that offers what I think is a great service. It's called Print Friendly and seems to do a decent job. They even offer a button you can put on your site (probably even on individual posts/pages). I'm hoping I can put something like it on this blog. Not that I have anything I think people really want to print out but you never know. I might come up with SOMETHING. :)
