Javascript and PHP to generate “live” print preview

Question

I want to be able to enter data and use Javascript onChange/onBlur/etc to render a "live" print preview; with page breaks. The ultimate goal is to have a PDF file that can be saved/emailed/etc that will be identical to the "preview". The data is to be stored in a MySQL database, I'm figuring AJAX to write it while entry.

Has anyone heard of a library (ideally free; purchase is an option) that can do this? If not, can you point me towards what can help me write something?

Answer 1

There are tons of PDF creation libraries for the PHP, you can easily google it.
