dompdf - The PHP 5 HTML to PDF Converter: Someone mentioned this over in the post on Prince. It looks quite good — they have a demo page where you can enter HTML in a box, then generate a PDF real-time. I tried it — it respects all CSS and generates a clean PDF.

Here’s some code, just to show how simple it is.

$html = "[an entire HTML document]";

$pdf = new DOMPDF();
$pdf->load_html($html);
$pdf->render();
$pdf->stream("hello_world.pdf");

It’s free, and needs nothing but PHP5 and the DOM extension.
