Since version 12, it has been able to generate accessible PDFs conforming to the PDF/UA profile (ISO 14289, the International Standard for accessible PDF technology) that can be used by people with assistive technologies.
Prince supports many languages, including Thai, Indic scripts (Hindi, Bengali, Tamil, etc.) and right-to-left scripts like Arabic and Hebrew.
In April 2003, Prince 1.0 was released, with basic support for XHTML, Cascading Style Sheets (CSS), Scalable Vector Graphics (SVG), and arbitrary XML. This first version was a command-line program that supported Microsoft Windows and Linux; there was no graphical user interface for Windows yet.
Before June 2012, Prince could only consume XML, but since the release of Prince 8.1 with an HTML parser, Prince can print web documents from HTML as well as XML and SVG.
In subsequent releases, CSS support was steadily extended until it was comparable with web browsers such as Opera and Firefox. It has also been expanded to support additional platforms—the latest offering include packages for macOS, FreeBSD, and Solaris. Wrappers are available for Java SE, .NET Framework, ActiveX, PHP, Ruby on Rails and Node.js to help integrate Prince into websites and apps.

Prince was developed using the Mercury functional logic programming language.
Prince has good support for CSS (including CSS Flexible Box Model, from Prince 12) with proprietary extensions for print-related functionality not currently in the CSS standard (for example, footnote policies, specifying the size of the bleed area of the page when crop marks are enabled, creating running page headers and footers and similar).
Prince supports most of ECMAScript 5th edition, but not strict mode. Later editions of ECMAScript are not supported.
