As it turns out, Windows updates had recently caused an error with network printers in addition to security vulnerabilities that surrounded the area. While Microsoft released an update to resolve the issue, it didn’t actually do much and the problem remained. However, there is an update that has happened to fix the issue. In addition to this, there are also cases where the problem may not be caused due to the Windows update but rather another problem on your end. Do not fret as we have additional workarounds here as well that can help you resolve the problem in case the problem wasn’t really caused by installing a Windows update in the first place. With that said, let us get started and show you the different methods that you can implement to fix the error in question. 

Check Domain Authentication

The first thing that you should try when you encounter the 0x00000520 error code while connecting to a printer is to check the authentication of the domain that you are trying to connect to. As it turns out, the error code in specific refers to the fact that the specified login session was not found, or it was terminated.  Therefore, if this case is applicable to you, the first thing that you should do is to check your domain authentication and make sure that everything is fine there. In case the issue is not being generated by an issue with domain authentication, simply move on to the next method down below.

Check Network Settings

As it turns out, another possible thing that can cause the problem in question is your network settings. The problem can arise when your public and private network settings are not updated in which case you will have to double-check them and see if that could be causing the issue. Make sure that your computer is allowed to be discoverable by other devices on your network.  In order to check your network settings, follow the instructions that are given down below:

Install Windows Update

Finally, if none of the above-mentioned methods have helped you in solving the 0x00000520 error code, then it is very likely that the problem is being caused by an installed Windows update.

The reason being that Microsoft has already released an update that will fix the network printer issues for you and all you need to do is simply download and install it on your computer. The update that we are talking about is referred to as KB5006674. Thanks to Microsoft Update Catalog, you can simply search up the update via the provided ID and it should be available to download.
