2. Right-click on the relevant printer queue and choose Remove device

2. Type in your Admin password.

3. Select Yes when promted.

4. Disconnect and then reconnect the printers USB cable. This will create a new printer queue and should resolve the issue.

Method #3
Switch to a local user while signed in as a user with administrator. 

• This method will leave the administrator user signed in.

1. Completely Shut down the computer

2. Start computer back up and sign in as Admin

3. Open the printer queue to the printer.

4. Go to Windows 10 Start button and sign in as a Local user but DO NOT log out of Admin account on the computer. Printer should now work without issues.
