Windows 10's September security update caused network printing problems (0x0000011b). Hopefully with the October security update Microsoft will fix this error.
But no, Microsoft's October security update not only failed to fix error 0x0000011b, but also made the situation worse. Operation could not be completed (error 0x00000709).

To fix printer sharing in LAN in Windows 10, you must fix the error on both the server and the client. You can apply one of two ways to fix it:

Method 1:
At the server and client, remove update KB5006670, by:

Open Control Panel click Programs and Features click View installed updates, Uninstall the latest Windows update, specifically the Security update for Microsoft Windows (KB5006670).

Then restart the server and client, the problem should be solved.

Method 2:
- At the server:
Open the Windows Registry Editor (open Run, type regedit) and navigate to the:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Print
Create a new DWORD-32 bit value named RpcAuthnLevelPrivacyEnabled, and set it to 0. (You can download the attached reg file below).

Then restart the server.

- At the client:
Open the Windows Registry Editor (open Run, type regedit) and navigate to the:
HKEY_LOCAL_MACHINE \Software\Policies\Microsoft\Windows NT\Printers\PointAndPrint
Create a new DWORD-32 bit value named RestrictDriverInstallationToAdministrators, and set it to 0. (You can download the attached reg file below).

Then restart the client, the problem should be solved.
