of the older GDI-based spooler. The XPS print spooler can produce better quality prints for printers that directly consume the XPS format. Third-party software Hardware XPS had the support of printing companies such as Konica Minolta, Sharp, Canon, Epson, Hewlett-Packard, and Xerox and software and hardware companies such as CSR (formerly Zoran), and Global Graphics. Native XPS printers were introduced by Canon, Konica Minolta, Toshiba, and Xerox. Devices at the Certified for Windows level of Windows Logo conformance certification were required to have XPS drivers for printing since 1 June 2007. 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, Monotype Imaging announced it had licensed its XPS-to-PCL 6 and XPS-to-PostScript vector conversion filters to Microsoft for use in the next version of Windows. History and standardization In 2003, Global Graphics was chosen by Microsoft to provide consultancy and proof of concept development services on XPS and worked with the Windows development teams on the specification and reference architecture for the new format. Microsoft submitted the XPS specification to Ecma International. In June 2007 Ecma International Technical Committee 46 (TC46) was set up to develop a standard based on the Open XML Paper Specification (OpenXPS). At the 97th General Assembly held in Budapest, June 16, 2009, Ecma International approved Open XML Paper Specification (OpenXPS) as an Ecma standard (ECMA-388). TC46's members included: Autodesk Brother Industries Canon CSR (formerly Zoran) Fujifilm Fujitsu Global Graphics Hewlett Packard Konica Minolta Lexmark Microsoft
