I’ve added a small little thing to print entries. I’m not sure how often this might be used, but it’s Really easy to set up. Here’s what I did to accomplish this.

1. Create a new Template. I modeled mine after the comments template, and took out all references to comments.
2. Format the Template to what you want to be displayed. (I just made mine a simple page with just the entry, author, and date/time.
3. Now, on your comments page, you’ll want to put this line (copy and paste what’s in the textbox):

   <a href=”javascript:void(0);” onclick=”window.open(‘{trackback_path=”weblog/[printable_template_name]“}’,'printwindow’,'width=400,height=500,status=0,scrollbars=1,resizable=1,location=0′);” title=”Printable”>Print This</a>

4. Notice that it does use the {trackback_path=} instead of a normal {path=}. This is because EE will append the entry ID automatically for the trackback, but not for simple path.
5. Make sure that you do change the [printable_template_name] to the Template you just created.

That’s it! Now clicking on the “print this” link, it should open a window that displays your printer friendly entry!
