How to Install Brother MFC-8660DN (COM4) Driver

1. Check your Windows version. Open your system information and confirm whether Windows is 32-bit or 64-bit. For Windows 10/11 systems, check compatibility carefully: Windows 10 is listed as supported here, but Windows 11 support should not be assumed.
2. Choose the matching package. Before starting your Brother MFC-8660DN (COM4) driver download for Windows, verify the model, supported operating system, and package details. Choose the latest version compatible with your setup, rather than simply the newest release.
3. Download and prepare the installer. Use a trusted, free download source, preferably Brother’s official support resources. If the package is compressed, extract it before running setup.
4. Install the driver. Run the installer and follow its prompts, connecting the printer when instructed. If you use a network connection, ensure the computer can reach the printer. The “COM4” label may reflect a local device or port assignment; do not select that port unless it matches your actual configuration.
5. Verify printing. Open Windows printer settings, confirm the correct printer and port are selected, and print a test page. If printing fails, check the connection and queue before reinstalling.

Keep your driver updated by checking for a compatible update when printing problems arise or your Windows installation changes. Review compatibility notes before replacing a working driver, and remember that older Windows versions may no longer receive new driver releases.
