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.

In case the issue is not being generated by an issue with domain authentication, simply move on to the next method down below.
