Windows cannot connect to the printer operation failed with error 0x00011b

How to fix the 0x0000011b printing errors

To fix the recent 0x0000011b printing errors without removing the current Windows Updates (KB5005565), you can instead disable the CVE-2021-1678 mitigation enabled by default this month.

To do that, open the Windows Registry Editor and navigate to the HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Print key, create a new DWORD-32 bit value named RpcAuthnLevelPrivacyEnabled, and set it to 0, as shown in the Registry file below.

Windows Registry Editor Version 5.00[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Print]"RpcAuthnLevelPrivacyEnabled"=dword:00000000

To make it easier to add this change, you can use the fix-0x0000011b.reg Registry file to add it for you.

Download this file on both your print server and your Windows devices connecting to it, double-click on it, and allow the data to be merged.

And Close Registry File.

Open Service and restart Print Spooler
