Gregg,
Thanks for asking.
There IS a way to achieve what you want achieved - the information submitted in a form sent to a Fax machine. You need to expand your thinking to see it where it hides right in front of you.
Have the Form sent to an email address which Auto-redirects to an email-to-fax service like...
http://maxemail.com
http://www.faxaway.com
... and others. Google "Email to fax" or something along those lines.
