Fix: ‘Windows couldn’t connect to the printer’ on Windows 11

A lot of Windows are reporting that they’re no longer able to connect to their network printer after installing the KB5006746 update on Windows 11. Upon trying to print something, affected users see an error prompt with the error message ‘Windows couldn’t connect to the printer‘.

The irony of this ongoing issue is that the KB5006746 update was supposed to fix a whole slew of printer connectivity issues that we’re preventing Windows 11 users from connecting to their network printers.

And while this update was successful for the most part, a small segment of the user base ended up with an entirely new issue where their network printer became entirely unusable.

Fortunately for those of you affected by this issue, there are actually a number of potential fixes that you can deploy in order to make your network printer usable once again. Here’s a list of fixes that other affected users have successfully used to fix the functionality of their network printer after installing the KB5006746 update:

Now that you are aware of every potential fix that is capable of allowing you to finally connect your network printer to the internet, move down to the first potential fix below.

Install ‘the Fix’ of the Fix

Microsoft was quick to announce a fix to the fix (the KB5006746 update) that introduced this new slew of issues for people that are using a network-connected printer.

If you had no issues connecting to your network printer and you’re suddenly no longer able to after you installed the KB5006746 update, the first thing you should do is check Windows Update to see if a new update is available.

Microsoft has already announced that they have started deploying a hotfix for the KB5006746 update in order to resolve the unexpected consequences.

If you are affected, follow the instructions below to install the hotfix for the KB5006746 update and resolve your issue with the network connected printer:

Note: Because Microsoft releases these hotfixes on segments, it’s possible that you haven’t yet received the hotfix while others have. If no new update is available yet, check back regularly or move down to the next potential fix below.

1. Press Windows key + R to open up a Run dialog box. Next, type ‘ms-settings:windowsupdate’ inside the text box and press Enter to open up the Windows Update tab of the Settings menu on Windows 11.

   

2. Once you’re inside the Windows Update screen, move down to the right-hand section and click on Check for Updates to check if the hotfix is ready to be installed.

   

3. If a new update is waiting to be installed, click on Install Now and wait patiently until the new hotfix gets installed locally.

   

4. Once the update is installed, reboot your PC and attempt to connect your network printer once again after your computer boots back up.

In case this issue didn’t resolve the problem in your case or no new update is available inside WU, move down to the next potential fix below.

Run the Printer Troubleshooter

In case the problem is not actually related to the KB5006746 update, chances are you’re dealing with this problem due to a general inconsistency that is in no way related to this bad update that has gotten everybody riled up.

If your particular problem has nothing to do with the KB5006746 update, the best thing you can do is run the Printer Troubleshooter and apply the recommended fix.

Note: Upon running the Printer Troubleshooter utility, the tool will start scanning your current printing components for any inconsistencies it can find. If a recognizable problem is identified, the tool will then suggest the appropriate automated fix that you can typically enforce in just one click.

Follow the instructions below for step-by-step instructions on running the Printer Troubleshooter and applying the recommended fix:

1. Open up a Run dialog box by pressing Windows key + R. Next, type ‘ms-settings:troubleshoot‘ inside the text box and press Enter to open up the Troubleshoot tab of the Settings app.

   

2. Once you’re inside the Troubleshoot tab, click on Other Troubleshooters from the menu on the right-hand side.

   

3. Once you’re inside the Other Troubleshooters menu, click on the Run button associated with the Printer.

   

4. At the initial screen, wait until the scan is complete. If a viable issue is identified, you will be presented with a screen when you can apply the recommended fix.
5. If a viable recommended fix is pushed forward by the troubleshooter, click on Apply this fix to enforce it.

   

   Note: Depending on the fix that gets recommended, you might be required to do some manual steps – just follow the on-screen instructions.

6. Reboot your PC and see if you are now able to connect to your network printer.

In case no viable printer fix was recommended or you already enforced it and you saw no improvement to the printer network connectivity, move down to the next potential fix below.

Re-Enable the Print to PDF feature

As it turns out, you can also expect to see this particular issue occurring due to a complementary feature (Print-to-PDF) that was unexpectedly affected by the latest update that you installed.

According to some affected users, your inability to connect to a network printer might be related to the Print to PDF feature that ended up being disabled after the installation of the update.

if this scenario is applicable, follow the instructions below to re-enable the Print to PDF feature from the Windows Features screen:

1. Press Windows key + R to open up a Run dialog box. Next, type ‘appwiz.cpl’ inside the text box and press Enter to open up the Programs and Features menu.

   

2. Once you’re inside the Programs and Features menu, use the menu on the left to click on Turn Windows features on or off.
   

   

3. When you’re prompted by the User Account Control (UAC), click Yes to grant admin access.
4. Once you’re inside the Windows Features screen, scroll down to the Microsoft Print to PDF and enable the checkbox associated with it before clicking on Ok to save the changes.

   

5. At the confirmation prompt, accept the change and wait until the Microsoft Print to PFF component is enabled.
6. Reboot your PC and see if you are still not able to connect your network printer.

In case the same kind of issue is still occurring, move down to the next potential fix below.

Uninstall the KB5006746 update

If none of the methods above have proven to be effective in your case, one way to be certain that you eliminate the effects brought about by the bad Windows 11 update is to simply uninstall the problematic KB5006746 update via the Update History Tab.

However, doing this is likely not enough since the Windows Update component will likely end up re-installing the problematic update once again. Because of this, you’ll also need to use the Microsoft Show or Hide troubleshooter to hide the update that is causing this issue for you.

Note: Keep in mind that if the KB5006746 update was installed weeks ago, you will likely not be able to uninstall it at this point. In this case, the only thing we can do

Follow the instructions below to uninstall and hide the KB5006746 update in order to fix the issue related to your network printer:

1. Press Windows key + R to open a Run dialog box. Next, type ‘appwiz.cpl’ inside the text box and press Enter to open up the Programs and Features screen.

   

2. Once you’re inside the Programs and Features menu, use the vertical menu on the left to click on View installed updates.
   

   

3. Once you’re inside the Installed Update screen, right-click on the KB5006746 update and choose Uninstall from the context menu.

   

4. At the confirmation prompt, click Yes, then wait until the uninstallation is complete.
5. Once the KB5006746 update is uninstalled, don’t restart your computer. Instead, visit the official download page of the Microsoft Show or Hide troubleshooter.
   Note: The download should start automatically.
6. After the download is complete, open the .diagcab file and click on the Advanced button at the first prompt. Next, check the box associated with Apply Repairs Automatically before clicking on Next.

   

7. Wait until the utility scans your system to figure out which pending updates are not installed. Once the next screen appears, click on Hide Updates from the list of available options.

   

8. From the next screen, check the box associated with the KB5006746 update, then click on Next to hide it – this will prevent the Windows Update from attempting to install the update once again.
9. Reboot your PC one final time and see if you are now able to connect your network printer without receiving the same ‘Windows couldn’t connect to the printer’.

If the same kind of issue is still occurring or this method was not applicable, move down to the final potential fix below.

Enforce the Fix Manually via Registry Editor

In case you were not able to follow the method above due to the fact that the installation of the problematic KB5006746 update was older than 2 weeks, you will no longer be able to uninstall it.

However, what you can still do is enforce the same kind of fix that the hotfix for the bad update already does.

This can be done by opening an elevated Registry Editor prompt and creating a new DWORD 32-bit key named RpcAuthnLevelPrivacyEnabled and setting it to 0.

Follow the instructions below for step by step instructions on how to do this:

1. Press Windows key + R to open up a Run dialog box. Next, type ‘regedit’ inside the text box and press Ctrl + Shift + Enter to open up the Registry Editor with admin access.

   

2. When you’re prompted by the User Account Control, click Yes to grant admin access.
3. Once you’re inside the Registry Editor tool, use the vertical menu on the left to navigate to the following location:

   HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Print

   Note: You can either navigate there manually or you can paste the full path above directly into the navigation bar at the top and press Enter to get there instantly.

4. Next, move over to the right-hand section – once you’re there right-click on an empty space and choose New > Dword (32-bit) Value.

   

5. Finally, name the newly created DWORD value to RpcAuthnLevelPrivacyEnabled, then double-click on it and set the Base to Hexadecimal and the Value data to 0 before clicking on Ok to save the changes.

   

6. Close the elevated Registry Editor utility and restart your computer in order to allow the changes to take effect.
7. Once your PC boots back up, attempt to connect your network printer once again and see if the issue is now fixed.
