I have google as much as I possible, checked stackoverflow several times, and yet I can not find a good html to pdf converter that can handle css. Is there a free and open source solution (even for commercial usage)? There are many solutions, with huge variety of price ranges, but I was looking for something open source and free. I have tried PISA for Python and it works fairly well, but is not free for commercial usage. Is there anything for .Net? I have not had success with iTextSharp.
I've wkhtmltopdf used on a couple of projects. http://code.google.com/p/wkhtmltopdf/. It uses the webkit rendering engine, which powers the Safari browser. You'll get completely up to date rendering just like a web browser with CSS and all.
Oh, and it's open source.
