Prince: Overview: There’s a big gap in getting Web content into print.
Prince is a system that lets you take XML, style it with CSS, and then generate a PDF. It’s very good — I’ve seen demos, and their site is full of them. Look at the image with this post — that’s HTML converted to PDF, unattended.
But it’s still expensive — $3,800 for a server license? Ouch.
Prince is a computer program that converts XML into PDF documents. Prince can read many XML formats, including XHTML and SVG. Prince formats documents according to style sheets written in CSS.
What are the free alternatives? It’s a pretty bare field. There’s XML:FO, but I never had much luck with that (and I detest XSL, which doesn’t help). Recently, I was impressed with FPDF, which is a PHP class that will generate simple PDFs from HTML.
