We chose Prince because it provides more features and generates higher-quality PDFs than any other library we tried. YesLogic, Prince's creator, pioneered CSS and HTML-based publishing technology with the first release of PrinceXML in 2003 and has been leading the category ever since.

Prince distributions are available on Windows, Linux, and Mac, with wrappers for ActiveX, C#, Java, NodeJS, PHP, and Ruby on Rails.
