Format

The XPS document format consists of structured XML markup that defines the layout of a document and the visual appearance of each page, along with rendering rules for distributing, archiving, rendering, processing and printing the documents. Notably, the markup language for XPS is a subset of

Comparison with PDF

Like Adobe Inc.'s PDF, XPS is a page description language using fixed-layout document format designed to preserve document fidelity, providing device-independent document appearance. PDF is a database of objects that may be created from PostScript or generated directly from applications, whereas XPS is based on XML. Both formats are compressed, albeit using different methods. The filter

architecture of XPS is also similar to the one used in printers supporting the PostScript page description language. PDF includes dynamic capabilities purposely not supported by the XPS format. There are many resources for converting from XPS to PDF and some for converting from PDF to XPS. A method often suggested is to open an XPS file in a program with printing capability, and then "print" to a virtual PDF printer such as Microsoft Print to PDF, with a similar procedure to convert from PDF to XPS.

Licensing

Microsoft released XPS under a royalty-free patent license called the ''Community Promise for XPS'', allowing users to create implementations of the specification that read, write and render XPS files as long as they included a notice within the source that technologies implemented may be encumbered by patents held by Microsoft. Microsoft also required that organizations "engaged in the business of developing (i) scanners that output XPS Documents; (ii) printers that consume XPS Documents to produce hard-copy output; or (iii) print driver or raster image software products or components thereof that convert XPS Documents for the purpose of producing hard-copy output, ..will not sue Microsoft or any of its licensees under the XML Paper Specification or customers for infringement of any XML Paper Specification Derived Patents (as defined below) on account of any manufacture, use, sale, offer for sale, importation or other disposition or promotion of any XML Paper Specification implementations." The specification itself was released under a royalty-free copyright license, allowing its free distribution. On September 13, 2011,
