Notice at the end of each blog post, you can look to the bottom left and PRINT PDF.
I have installed this widget right into the Blogger template.
It's a very handy tool and easier to use than the Adobe feature "print to pdf".
Give it a try:
Go to joliprint
Enter URL of the article you want to print out
Add the Joliprint bookmarklet to your browser's favorites bar, and make any webpage Joliprint ready.
