Consider the following scenario:
- You install a non-Standard Port Monitor (SPM) or non-Line Printer Resource (LPR) printer with a universal serial bus (USB) port.
- You use the Printbrm.exe command-line tool to export the printer settings.
- You import the printer settings to another computer.
In this scenario, the printer port for the restored printer is displayed as FILE. Additionally, if you plug the USB printer into the new computer, you are prompted through all steps of printer installation. After the printer is installed, you see a second instance of the printer on the new computer.
This problem occurs on computers that are running Windows Vista or Windows Server 2008.
