Windows 11 is transitioning to a standardized printing model based on the Internet Printing Protocol (IPP) and the Mopria Alliance certification standard. Starting with Windows 11 24H2, released in October 2024, Microsoft introduced the Windows Protected Print mode (WPP), which replaces traditional manufacturer-specific v3/v4 drivers with a standardized Microsoft IPP Class driver. This shift aims to enhance security by preventing the installation of third-party drivers and reducing the attack surface, as proprietary drivers have historically contributed to 9% of Windows security issues. WPP is based on IPP and requires Mopria-certified printers to function, ensuring compatibility with over 120 million certified devices.
The WPP mode is not enabled by default and must be manually activated by users through the "Settings" app under "Bluetooth and devices" > "Printers and scanners". Once enabled, it restricts printing to only Mopria-certified devices and uses the Microsoft IPP Class driver, which operates with user-level privileges instead of system-level rights, mitigating risks like those seen in the "Print Nightmare" vulnerability. For users who need advanced printer functions, manufacturer-provided tools may be available in the Microsoft Store as "Druckunterstützungs-Apps" (PSA), which are UWP-based extensions designed to enhance the functionality and appearance of the standardized drivers.
Microsoft has announced that by July 2026, IPP-Klassentreiber will become the default for all Mopria-certified printers on Windows 11, phasing out automatic installation of manufacturer-specific drivers. This move aligns with Microsoft's long-term strategy to standardize printing and improve security, a process that has been under development since at least 2021. The Mopria Alliance, originally founded by Canon, HP, Samsung, and Xerox, now includes all major printer manufacturers, ensuring broad industry support for the standard. Compatibility can be verified via the Mopria certification website.
