Page layout file containing information written in the XPS page description language developed by Microsoft; formatted like an .XML file and can define the layout, appearance, and printing information for a document.
XPS was designed as a replacement for the Enhanced Metafile (.EMF) format. It is similar to a .PDF file, but is based on XML instead of the PostScript language. XPS files can be created in Windows by selecting the "Microsoft XPS Document Writer" as the printer when printing a document.
XPS files can be opened with Microsoft's XPS Viewer, which is included with Windows Vista, Windows 7, and Internet Explorer 6 or later. It is also part of the XPS Essentials Pack, which can be downloaded from Microsoft and used with Windows XP.
