PDF on the fly

The project is to integrate a feature that converts a HTML page into a styled PDF. The website is template based PHP/MySQL. We only managed to build PDFs by importing static and un-styled HTML cache files into the FPDF script. This is a bad solution, not only because it lacks even basic styling like bold subheads etc. If you have managed a solution where basically a HTML page is output as a PDF file, please quote for this job. But please do abstain from bidding if you are not familiar with FPDF, TCPDF, jsPDF etc.
