Brother MFC-9120CN Remote Setup Port (COM12) Driver

The Brother MFC-9120CN Remote Setup Port (COM12) driver helps Windows recognize the USB-connected remote setup interface used by Brother software to communicate with your multifunction printer. It is relevant if you need to configure the device from your PC or troubleshoot a missing or unrecognized Remote Setup Port entry in Device Manager.

Key Features

• Remote setup communication: Supports the connection between compatible Brother setup software and the MFC-9120CN, allowing access to settings supported by that software.
• USB interface recognition: Helps Windows identify the remote setup port correctly rather than leaving it listed as an unknown device.
• Legacy Windows support: Intended for compatible installations of Windows 10, 8.1, 7, Vista, and XP. Select a package that explicitly lists your operating system and architecture.
• Part of the device software setup: Works alongside the appropriate Brother utilities. This port driver alone does not replace the printer and scanner drivers required for printing and scanning.

How to Install Brother MFC-9120CN Remote Setup Port (COM12) Driver

1. Check your Windows version. Open your system information and confirm whether you use a 32-bit or 64-bit edition. For Windows 10/11 systems, check support carefully: Windows 10 is listed here, but Windows 11 compatibility is not confirmed.
2. Choose a compatible package. Before starting your Brother MFC-9120CN Remote Setup Port (COM12) driver download for Windows, verify the model and supported OS. Look for the latest version that explicitly supports your configuration, and use a trusted source for a free download.
3. Prepare the connection. Turn on the printer and follow the package instructions about when to connect its USB cable. Close any running Brother setup utilities before installation.
4. Install the software. Run the downloaded installer with administrator permissions and follow its prompts. If the download contains only driver files, use Device Manager’s Update driver option and browse to the extracted folder.
5. Verify operation. Restart Windows if prompted, check Device Manager for warning icons, and test communication through compatible Brother Remote Setup software. Windows assigns COM numbers, so your port may appear with a number other than COM12.

Keep the driver updated when Brother provides a compatible update that addresses your setup or connection issue. Check the release notes before replacing a working installation, and remember that the latest version available may not support every older Windows edition.
