Why can't I print the finished website?

I need a button that when you press it sends out a form via email (this already exists) and then prints a custom page (not the stuff you see on the screen while pressing the button) but using the data...

Hello I couldn't find an option to add a button on a site to print the page or export it as a PDF. Is there an option like this?

Hi, I would like to request the feature to print a page / website, and the feature to export a website to high-quality full-page pdf
