Install all updates on both the PC sharing the printer and the PC connecting. If it persists, connect the printer directly over the network (Add a printer → by TCP/IP address) instead of via the shared PC. Avoid registry hacks that weaken printer security on networks you don't control.

What 0x0000011b means

0x0000011b arose from Microsoft’s fixes for the PrintNightmare vulnerabilities, which require stronger authentication between print clients and print servers. Mismatched update levels between PCs or old drivers cause the failure.

How it shows up

  • “Operation failed with error 0x0000011b” when adding a shared printer.
  • Printing to a shared printer stopped after updates.

Common causes

  • Print server and client at different update levels.
  • Legacy printer drivers.
  • Connecting through a shared PC rather than directly.

How to fix it, step by step

  1. Update both PCsInstall all Windows updates on the sharing PC and the connecting PC, then restart both.
  2. Connect directly by IPSettings → Printers & scanners → Add device → Add manually → Add a printer using an IP address or hostname.
  3. Update the driverInstall the latest driver from the printer maker on both PCs.
  4. Workplace networksAsk IT to deploy drivers via a print server; registry workarounds weaken security.
Check it's fixed: The printer adds successfully and prints a test page.

Keeping it from coming back

Keep all PCs on the same update level and prefer direct network printing.
