(PDF). However, PDF remained the standard choice, and support for and user familiarity with XPS files is limited. It has been described as neglected technology, which may cause difficulties to recipients of documents in a format they are not familiar with.

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 XAML, allowing it to incorporate vector elements in documents. An XPS file is a ZIP archive using the Open Packaging Conventions, containing the files which make up the document. These include an XML markup file for each page, text, embedded fonts, raster images, 2D

Features

XPS specifies a set of document layout functionality for paged, printable documents. It also has support for features such as color gradients, transparencies,

color spaces, printer calibration, multiple-ink systems and print schemas. XPS supports the Windows Color System color management technology for color conversion precision across devices and higher dynamic range. It includes a software raster image processor (RIP) (downloadable separately). The print subsystem supports named colors, simplifying color definition for images transmitted to printers supporting those colors. XPS supports HD Photo images natively for raster images. The XPS format used in the spool file represents advanced graphics effects such as 3D images, glow effects, and gradients as Windows Presentation Foundation primitives, which printer drivers could offload their rasterization to the printer in order to reduce computational load if the printer is capable of rasterizing those primitives.

Comparison with PDF

Like PDF, XPS is a page description language using fixed-layout document format designed to preserve document fidelity, providing device-independent document appearance. PDF uses Carousel Object Syntax (COS syntax) to form a random access database of objects that may be created from

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.

Viewing and creating XPS documents

and later supports both creating and viewing XPS. In addition, the printing architecture of Windows Vista uses XPS as the spooler format. Apps can create XPS documents by printing to XPS Document Writer, a virtual printer that comes bundled with Windows. These files open in XPS Viewer, an optional component that comes with Windows Vista and later. In Windows Vista, XPS is hosted within

Since then, Microsoft released the XPS Essentials Pack for Windows XP, Server 2003, and Vista, which includes the standalone viewer, an IFilter plug-in that helps Windows Desktop Search index the contents of XPS files, and another plug-in for Windows Explorer to help generate thumbnails for XPS files.

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,
