When you attempt to remove a printer port that is no longer in use, you may receive an error message saying “The requested resource is in use”. Try these steps to solve this issue.
To successfully remove the port and avoid this error, you will need to stop and restart the Print Spooler service. These steps assume you have already removed all printers that used the port you are removing.
- Hold down the Windows Key and press “R” to bring up the Windows Run dialog.
- Type “services.msc“, then click “OK“.
- Highlight the “Print Spooler” service, then click the “Stop” button.
- Once the service has stopped, select the “Start” button to restart the service.
Now you should be able to remove the printer port without error.
These steps can be used on Windows Vista, 7, 8, Server 2008, and Server 2012
