Today I discovered an awesome new tool called PrintFriendly. If you go to their website, you can enter a web site's URL to make it print friendly or generate a PDF version of it. This is awesome for so many things and you have such better control over the output than you do with a printer.
The even cooler thing is that you can put a link to this on your website or blog. You might notice the "Print/PDF" link at the end of all my blog posts now. I just stuck it in as the directions for Blogger said. If you click on that link for any of my posts you can generate a print friendly version of it with or without images and take out any sections of text you want. You can even tweet or email it, or make a PDF of it.
PrintFriendly is a really nifty tool especially for blogs. It's worth a look.
