Printing a post

Is there any simple way to print a single post? I'm working on a new build, and I wanted to print out "How to Ask for New Build Advice", Proximon's "A Guide to Choosing Parts", and Tecmo34's "Recommended Builds by Usage". I realize most posts aren't that long, but it's easier for me to read multiple pages on paper rather than a screen.

The only way I could figure out to print just the post was to copy-paste into a Word document. Am I missing something about how to print?

What you are doing is not "The wrong way" at all. You can also press Ctrl + P to print everything you see on the page while looking at it in your browser. Your way is more efficient and uses less ink.
