The Xerox Phaser 3330 XPS Windows driver is a specific printer driver designed to use XPS (XML Paper Specification) as the page description language for the Xerox Phaser 3330 printer. XPS is a Microsoft-developed format that is similar to PDF and is used for describing documents in a way that ensures they are printed accurately, regardless of the printer or device.

Using the XPS driver can provide benefits like better rendering of complex documents, enhanced print quality, and compatibility with features like duplex printing (double-sided) and better font management. This driver is often recommended for users who need high-quality output and are printing documents that make use of advanced layout features.
