How can I add print button to a form

I have a document that I want participants to be able to print out and take with them.  How do I add print page button.  I saw the option to turn it on for a different page but not the one I want to use the feature on.  

The approach to printing highly depends on what you wanted to print:

1. If you only want to print the form as is, without the user's data in it, just add a PRINT BUTTON to your form.

2. And if you want to print the form as is, but, with the user's data in it, you would utilize either the EDIT LINK on the Email Notification, or the PRINT BUTTON on the Submissions Page while editing a submission.
