About this tag
The usb print driver tag covers Windows security issues involving the operating-system component used by locally connected USB printers.

Coverage explains how Microsoft addressed these flaws through the July 14, 2026 Patch Tuesday updates, including supported Windows 11 releases and Windows Server 2025. It also identifies Usbprint.sys and emphasizes deploying the appropriate cumulative update rather than relying on disconnecting a printer as a mitigation.
