    After installing KB5005566, installation of printers using Internet Printing Protocol (IPP) might not complete successfully. Devices which had connected to and installed the printer prior to the installation of KB5005566 are unaffected and print operations to that printer will succeed as usual.

    Note: IPP is not commonly used by devices designed for home use. The printing environments affected by this issue are more commonly found in enterprises and organizations.

    Resolution: This issue has been resolved in KB5007189.

    Affected platforms:
    • Client: Windows 10, version 21H1; Windows 10, version 20H2; Windows 10, version 2004; Windows 10, version 1809; Windows 11, version 21H2; Windows 10, version 1909

    After installation of KB5006667, Windows print clients might encounter the following errors when connecting to a remote printer shared on a Windows print server:
    • 0x000006e4 (RPC_S_CANNOT_SUPPORT)
    • 0x0000007c (ERROR_INVALID_LEVEL)
    • 0x00000709 (ERROR_INVALID_PRINTER_NAME)
    Note: The printer connection issues described in this issue are specific to print servers and are not commonly observed in devices designed for home use. Printing environments affected by this issue are more commonly found in enterprises and organizations.
     
    Workaround: You can take steps to workaround this issue on print servers that meet the following prerequisite:
     
    • Print clients must have installed a Windows update released on or after January 2021 before the print server has installed KB5006667.
    Ensure that network security and VPN solutions allow print clients to establish RPC over TCP connections to print server over the following port range:
    • Default start port: 49152
    • Default end port: 65535
    • Port Range: 16384 ports
    Please refer to these articles for further guidance:
    You also benefit from using client side rendering for print jobs. The 'Render print jobs on client computers' option is available from the printer's device Properties, and it is recommended that its checkbox is selected on the print server. Note this step will not help if clients have overwrites which prevent the server setting from taking effect.
     
    Next steps: Microsoft is working on a resolution that will allow print clients to establish RPC packet privacy connections to print servers using RPC over SMB. We will provide an update once more information is available.
