Printing out your documents on Windows 10 or Windows 11 should be an easy task. You need to open your document and click the Print option or press the Ctrl and P keys. Unfortunately, printer error 0x0000011b may sometimes ruin your plans preventing you from connecting to your printer.

One of the best things about your Windows 11 PC is you can connect it to a networked printer for shared printer usage. Thus, you don’t need to buy individual printers at home, school, or work for printing purposes. But networked printing isn’t as easy as it sounds. Hackers are out there to target your Windows 11 PC and its printer network to infiltrate your personal or business files.

To prevent this, Microsoft pushed a new security patch to all Windows 11 and Windows 10 PCs. Though it did a great job in stopping hackers from intruding on your business or home computers, the networked printing system got broken for many users. Nothing to worry about it now as I’m going to share quick fixes below step-by-step so you can get back to work in no time.

What Is Windows Printer Error 0x0000011b?

The printer error 0x0000011b is a bug in the Windows 11, 10, 8, and 7 operating systems. It prevents your computer from connecting to a networked printer. A networked printer is a printer connected to an office, school, or home network via Ethernet or Wi-Fi routers. Any of the following versions of the error may show up when you try to connect your Windows PC with a shared printer or give a print command to a networked printer:

• Windows cannot connect to the printer

• Operation failed with error 0x0000011b

• Add Printer: Windows cannot connect to the printer. Printer error 0x0000011b

The problem started occurring to many Windows 11, Windows 10, etc., devices when Microsoft released the CVE-2021-1678 vulnerability security patch via over-the-air updates. The CVE-2021-1678 security loophole allowed hackers to use the Microsoft Remote Procedure Call (MSRPC) printer spooler to run malicious scripts on your Windows 11 or 10 PC remotely. CrowdStrike researchers discovered this serious threat for the first time.

The CVE-2021-1678 vulnerability mitigation patch started causing the printer error 0x0000011b on those Windows PCs that are not in a Windows domain with Kerberos setup. In large businesses and schools, the IT admin mainly uses a Windows domain network system to connect client computers, host servers, and shared printers. But in homes, small businesses, local shops, cyber cafes, etc., Windows domain networking is unavailable since it demands extra investments. Therefore, the “Operation failed with error 0x0000011b” error is prevalent in small networked organizations, schools, shops, or homes.

Disable Print Spooler RPC Encryption or CVE-2021-1678 Fix

Before you go ahead with this method, you must know that you should disable the CVE-2021-1678 fix if you’re certain that you’re using one of the best antivirus for Windows 11. Also, Registry Editor tweaks come with added complexities. You may accidentally modify other Registry keys or values which in turn may cripple the system. Thus, follow the steps mentioned carefully. If unsure, don’t apply the Registry fix yourself.

To fix the error code 0x0000011b related to networked or shared printers, Microsoft says you should disable the print spooler privacy settings on both the Client PC (from which you work) and Print Server (Workstation to which the printer is attached). When the RpcAuthnLevelPrivacyEnabled Registry key is set to 1, Windows automatically encrypts RPC communication with network printers and print servers. Disable this option to get rid of error code 0x0000011b. Here’s how:

• Hit Windows + R keys to open the Run command tool.

• Type regedit in the Open command box and hit Enter.

• Navigate to the Print Registry key directory either manually or by entering the following path into the Registry Editor address field:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Print

• Right-click on the Print key and select New→  DWORD-32 bit Value.

• Name the new key as RpcAuthnLevelPrivacyEnabled.

• Double-click on the new key and set its value to 0 (zero).

• Restart your computer.

• Perform the above steps on the host printer server as well.

Now, try to print again and see if it works. If you couldn’t connect to the networked printer yet, try connecting the printer and then print a test page.
