You can embed this code into your page. Also if you search the web, you'll likely find other embeddable codes as well. Most of these will work will for printing the viewable web page, but I don't think you'll find an option that prints just the blog posts.
Thanks. It would be easier if you just gave a Print option instead of me having to add the code. Anyhow, I did add to the pages that I thought someone might want to print. It's unfortunate that I can't allow them to print each individual blog.
