This plugin adds an icon to all posts which links to Print-Friendly page with a content of the post.
The CSS for the printed page is really poor. The print button appears only at the bottom of post/pages. I've been using Chan & Campbell's WP-Print. I only had to add "target _blank" and it works fine. What none of the print-type plugins tackle is the CSS issue. So, this one works but it doesn't standout.
