“Printer settings could not be saved. Error 0x000006d9”
on Windows

I was trying to share a printer with somebody in my house on the same network and when I tried to set it up, I received an error "Printer settings could not be saved. Operation could not be completed (error 0x000006d9)." Could you help?

Printers are often a critical part of everyday tasks, but encountering errors during configuration can lead to frustration. One such issue is the error message that reads: "Printer settings could not be saved. Operation could not be completed (error 0x000006d9)." 

The error prevents you from saving or updating printer settings, which can disrupt workflows and leave the printer unusable in certain scenarios. It commonly occurs when trying to share a printer or adjust its configuration settings within Windows, presenting a clear obstacle to completing the operation successfully.

The root causes of the 0x000006d9 error often lie in the system's services or configurations. A frequent culprit is the Windows Firewall service, which, when disabled, interrupts the management of shared resources like printers.

The error can also be caused by corrupted or incorrectly configured printer registry entries that may prevent communication between the printer and the system. It can also be caused by outdated drivers, insufficient permissions, or recent system updates related network settings; these add layers of complexity in diagnosing the problem.

To troubleshoot printer error 0x000006d9, you have to address the root cause. Enabling the Windows Firewall service is a common first step because it has an important role in managing network connections and printer sharing.

Moreover, making sure the printer drivers are up-to-date, perusing through the permissions, and then looking into the registry of the system for errors often solve such problems. Occasionally, a little advanced troubleshooting might become required: resetting services, or perhaps even digging through the configurations of a system.

For a simpler approach, using [d1] PC repair can identify and fix underlying issues automatically, saving time and effort while restoring normal printer operations.

Fix 1. Enable Windows Firewall service

The Windows Firewall service is essential for managing shared resources and ensuring secure communication over the network. If this service is disabled, the system may block operations related to printer sharing, resulting in the error. Enabling it restores the required functionality.

• Type Services in Windows search and press Enter.
• Locate Windows Defender Firewall in the list.
• Right-click it and select Properties.
• Under Startup type, select Automatic from the list.
• Click Start if the service is not already running.
• Press Apply and then OK to save changes.

If you can't modify Windows Defender Firewall service (grayed out), you can modify Registry settings instead, although make sure you make a back up before performing any modification to the database.

• Type regedit in Windows search and press Enter.
• Navigate to the following location:
  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MpsSvc
• Locate the Start key in the right panel.
• Double-click the Start key, change the value data to 2, and click OK (value 2 sets it to Automatic).
• Close the Registry Editor and restart your computer.

Fix 2. Update printer drivers

Outdated or incompatible printer drivers may cause your system to not communicate well with the printer, hence the error. Update the drivers for compatibility and to ensure no more driver-related issues.

• Right-click on the Start menu and select Device Manager.
• Expand the Printers section.
• Find your printer in the list, right-click on it, and select Update driver.
• Choose Search automatically for drivers.
• Follow the on-screen instructions to complete the update process.
• Restart your computer after the driver update is completed.
• Alternatively, you can always employ an automatic driver updater such as [rev id="DriverFix"] for all your driver updates.

Fix 3. Check printer sharing settings

Incorrect sharing settings can block the operation, especially if network sharing permissions are misconfigured. Ensuring the settings are properly adjusted can resolve the error.

• Type Control Panel in Windows search and press Enter.
• Under View by, select Small icons from the from down menu.
• Go to Devices and Printers.
• Right-click your printer and select Printer properties.
• Navigate to the Sharing tab.
• Check the box for Share this printer and click OK.

Fix 4. Reset printer spooler service

The printer spooler handles print jobs and interacts with the printer. Sometimes it fails and needs a reset to sort out the problem and get rid of any stuck processes.

• Type Services in Windows search and press Enter.
• Find the Print Spooler service in the list, right-click on it, and select Stop.
• Once the service has stopped, press the Win + R.
• Type %WINDIR%\system32\spool\printers and press Enter. This should open the Printers folder.
• Delete all files within this folder.
• After clearing it, go back to the services window, find the Print Spooler service, right-click on it, and select Start.
• Close the services window and attempt to print your document again.

Fix 5. Reset the TCP/IP settings and flush DNS

Sometimes, issues with the network can affect printer sharing, resulting in the 0x000006d9 error. Performing a TCP/IP stack reset and DNS flush can fix any connectivity problems that may trigger the error.

• Type cmd in Windows search.
• Right-click on the Command Prompt result and select Run as administrator.
• Copy and paste each of the following commands, pressing Enter every time:
  ipconfig /flushdns
  ipconfig /registerdns
  ipconfig /release
  ipconfig /renew
  netsh winsock reset
• Reboot your device.

Fix 6. Repair corrupted system files

If some of the important system files are corrupted, it might prevent printer from communicating via the network. Try running SFC and DISM scans that could help you resolve this problem.

• Open Command Prompt as administrator.
• Copy and paste the following command and press Enter:
  sfc /scannow
• Wait till the scan is finished. If Windows finds system file integrity violations, it will attempt to fix them. After this, use the set of the following commands, pressing Enter after each:
  DISM /Online /Cleanup-Image /CheckHealth
  DISM /Online /Cleanup-Image /ScanHealth
  DISM /Online /Cleanup-Image /RestoreHealth
  
• (Note: if you get an error executing this last command, add /Source:C:\RepairSource\Windows /LimitAccess to it and try again).
• Close down the Command Prompt and restart your device.
