Prince (software)
software product, XML + CSS formatter, from YesLogic, formerly Prince XML
Prince (formerly Prince XML) is a computer program that converts XML and HTML documents into PDF files by applying Cascading Style Sheets (CSS). Prince is a commercial product, which is free to download and use for non-commercial purposes.
Prince supports all common web standards, including HTML, CSS and JavaScript, through its own code. That is, Prince is not based on a browser engine, but implements its own engine.
Prince can 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.
Prince is developed by YesLogic, a small company based in Melbourne, Australia. Since 2004, Håkon Wium Lie, the co-creator of CSS, has been chairman of the board.
History
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.
In December 2005, Prince 5.1 passed the Acid2 test from the Web Standards Project.
This brief starts where responsible research should: with the source description of “Prince (software)” as software product, XML + CSS formatter, from YesLogic, formerly Prince XML. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as software product, XML + CSS formatter, from YesLogic, formerly Prince XML. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Aug 14, 2026. The linked authority identifier is Q7244299. 3 of 3 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2004, 2003 and 2005.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
