is a proprietary software program that converts XML
documents into PDF
files by applying Cascading Style Sheets
(CSS). It is developed by YesLogic, a small company based in Melbourne, Australia
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
; there was no graphical user interface
for Windows yet.
In subsequent releases, CSS support was steadily extended until it was comparable with web browsers such as Opera
and Mozilla Firefox
. As of January 2007, Prince surpassed common web browsers in support for paged media, CSS selectors, and generated content, including advanced facilities such as language-dependent hyphenation
dictionaries. It has also been expanded to support additional platforms—the latest offering include packages for the Apple Mac
, and Solaris
In December 2005, Prince 5.1 passed the Acid2
test from the Web Standards Project
. It was the third user agent
to pass the test, after Safari
The latest release of Prince is Prince 7.1, released in May 2010..
Prince was developed using the Mercury
functional logic programming language.
