        Printing and scanning might fail when these devices use smart card (PIV) authentication.

        On July 13, 2021, Microsoft released hardening changes for CVE-2021-33764. This might cause this issue when you install updates released July 13, 2021 or later on a domain controller (DC). The affected devices are smart card authenticating printers, scanners, and multifunction devices that don’t support DH or advertise support for des-ede3-cbc (“triple DES”) during the Kerberos AS request. Per section 3.2.1 of RFC 4556 spec, for this key exchange to work, the client has to both support and notify the key distribution center (KDC) of their support for des-ede3-cbc (“triple DES”). Clients who initiate Kerberos PKINIT with key-exchange in encryption mode but neither support nor tell the KDC that they support des-ede3-cbc (“triple DES”), will be rejected. ..

        Note Devices that are affected when using smart card (PIV) authentication should work as expected when using username and password authentication…

        Not seen it reported by anyone, so I don’t think many hit this issue other than Enteprises.
