Converting HTML to PDF via PHP

I have found various online tools that do this but nothing that has documented it as a tutorial so I can understand it.  I found the html_to_pdf.inc.php script that is entirely undocumented so I am not sure how to use it exactly. 
I am trying to export generated HTML (an invoice for a customer) to a saveable PDF that is downloaded.  Any ideas?
