How to Fix Windows Printer Sharing Error 0x0000011b (Windows 10 & 11)

If you have tried connecting to a shared printer over a local Windows network recently, chances are you have encountered the infamous error message:

Windows cannot connect to the printer. Operation failed with error 0x0000011b.

This single error code has disrupted millions of office, school, and home networks worldwide. It turns a previously working shared USB printer into an unreachable brick for secondary laptops and desktop computers.

In this guide, we’ll explain what caused this error, examine the risks and pitfalls of common registry “fixes,” and show you the permanent, zero-vulnerability solution using modern driverless network sharing.

What Causes Error 0x0000011b?

To understand error 0x0000011b, we need to look back at PrintNightmare (CVE-2021-1678 and related CVEs).

Historically, Windows shared printers across local networks using SMB (Server Message Block) and the Point and Print protocol. When a client PC connected to a shared printer on another PC, the host machine automatically transmitted printer driver files over the network to the client.

Security researchers discovered that attackers could exploit this mechanism to execute arbitrary code with full SYSTEM privileges on networked machines.

In response, Microsoft rolled out security updates (starting with cumulative update KB5005565) that enforce strict RPC (Remote Procedure Call) authentication and encryption levels (RpcAuthnLevelPrivacyEnabled) on the Windows Print Spooler.

When a client computer running Windows 10 or Windows 11 attempts to connect to a host machine that does not negotiate matching RPC privacy parameters, Windows blocks the connection immediately and displays Operation failed with error 0x0000011b.

Why Common Workarounds Fail

If you search forums or YouTube, you will frequently see a registry workaround recommended:

[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Print]
"RpcAuthnLevelPrivacyEnabled"=dword:00000000

While adding this registry key may temporarily restore printer sharing, it introduces three major problems:

1. Security Vulnerability: Setting RpcAuthnLevelPrivacyEnabled to 0 disables mandatory RPC packet encryption, intentionally leaving your Windows spooler vulnerable to network-based spoofing and privilege escalation.
2. Monthly Update Resets: Windows cumulative updates frequently enforce or reset spooler security policies. After the next Patch Tuesday update, your registry key may be ignored or cleared, breaking the printer connection all over again.
3. Cross-Platform Incompatibility: Legacy SMB printer sharing only works for Windows clients. It cannot provide printing for iPhones, iPads, Android phones, or Chromebooks.

The Permanent Fix: Modern Driverless IPP Sharing

Instead of weakening your Windows security to accommodate legacy SMB protocols, the permanent solution is to switch the underlying transport protocol from SMB to IPP (Internet Printing Protocol).

IPP Everywhere is the global standard created by the Printer Working Group. It powers:

• Apple AirPrint (iOS & macOS)
• Mopria Print Service (Android & Windows)
• Driverless Network Printing in Windows 10 and 11

Because IPP runs over HTTP (Port 631) using standard MIME documents and does not rely on Windows SMB/RPC driver push, it is completely immune to error 0x0000011b.

Step-by-Step: Share Your Printer via IPP with Printman

Printman is a zero-dependency, open-source tool for Windows that transforms your host PC into a native IPP / AirPrint print server in one command.

Step 1: Download Printman on the Host PC

On the Windows PC connected directly to the printer:

1. Go to the Printman Downloads.
2. Download the Standalone ZIP (printman-win-x64-standalone.zip).
3. Extract printman.exe into a folder such as C:\Tools\Printman.

Step 2: Start Network Sharing

Open PowerShell or Command Prompt and run:

.\printman.exe share

Printman will:

• Discover all installed printers on your Windows machine.
• Start an embedded IPP server on port 631.
• Broadcast Bonjour (mDNS) records across your Wi-Fi/Ethernet network.

[INFO] Broadcasting IPP Everywhere / AirPrint / Mopria profiles...
[INFO] Ready for incoming jobs on http://192.168.1.150:631/printers/HP_LaserJet

Step 3: Connect Client Windows PCs Without SMB Errors

On any client PC that previously threw error 0x0000011b:

1. Open Settings → Bluetooth & devices → Printers & scanners.
2. Click Add device.
3. Windows will discover your shared printer automatically via mDNS / IPP.
4. If connecting manually, click The printer that I want isn’t listed, select Select a shared printer by name, and enter:

   http://192.168.1.150:631/printers/YourPrinterName

5. Click Next. Windows installs the connection cleanly using native IPP.

No RPC error. No 0x0000011b. No registry modifications.

Bonus: Native Mobile Printing Included

Because Printman advertises genuine AirPrint and Mopria profiles alongside IPP, you can now also print directly from any iPhone, iPad, or Android phone on the same Wi-Fi network:

• On iOS: Tap Share → Print. The printer appears in the native AirPrint picker.
• On Android: Tap Print. The default Mopria print service prints directly to the printer.

Summary Checklist

Method	Vulnerable to 0x0000011b?	Security Risk?	Mobile Compatible?
Legacy Windows SMB Sharing	Yes (Frequent)	High (PrintNightmare)	No
RpcAuthnLevelPrivacyEnabled Registry Hack	Temporarily fixed until next update	High (Disables encryption)	No
Printman IPP Share (printman share)	Never	Zero (Standard IPP)	Yes (iOS, Android, Mac)

Say goodbye to 0x0000011b for good by moving your local network printing to modern open standards.
