  • Now, navigate back to the Services and restart the print spooler service.

A too-strictly configured Firewall can prevent your printing machine from interacting with your computer, causing printer problems. Hence, temporarily disabling it can solve the problem. You can follow these steps to do it. 

  • Firstly, click on the Start icon and look for Windows Security. 
  • Now, choose Windows Security from the list of results. 
  • Select Firewall & network protection from the available options. 
  • Now, turn off Windows Firewall for Private network or Public network profiles.
