The Brother DCP 390CN Printer driver allows Windows to communicate with your printer, send print jobs, and apply the correct printing settings. For an Ethernet-connected setup, it also helps your computer use the printer over your local network. Choose a driver package that matches your Windows version before downloading.

Key Features

• Network printing: Connect to the Brother DCP 390CN through your local network so computers with the appropriate driver can send documents to the printer.
• Print controls: Adjust available options such as paper size, media type, print quality, and color settings to suit everyday documents or photo printing.
• Device recognition: Helps Windows identify the printer correctly instead of relying on a generic driver with limited functionality.
• Multifunction support: A compatible full driver and software package may include scanning components as well as the printer driver. Check the package description if you need both functions.

How to Install

1. Check your Windows system. Confirm whether you use Windows 11, 10, 8, or 7, and check your system type. Select a download explicitly listed as compatible with that version and architecture; an older driver is not automatically suitable for a newer operating system.
2. Prepare the printer connection. Turn on the Brother DCP 390CN and connect its Ethernet port to your router or network switch. Make sure your computer is on the same local network.
3. Download and open the installer. Save the matching Brother driver package, extract it if necessary, and run the setup file. Approve the Windows administrator prompt if one appears.
4. Complete the network setup. Choose the network connection option when prompted and select your printer from the detected devices. If it does not appear, check the Ethernet cable and network connection, or use its IP address if the installer offers manual entry.
5. Verify operation. Finish setup, restart Windows if requested, and print a test page from the printer’s settings. If you installed scanning software, test a scan separately to confirm that component is working too.

Common Issues and Fixes

• Install fails or stalls: Uninstall any previous Brother DCP-390CN/MFL-Pro Suite software, run the installer as administrator, and temporarily disable antivirus. Reboot before retrying; use the correct 32-bit or 64-bit package for your Windows version.
• Printer not detected: For USB, connect the DCP-390CN directly to the PC—not a hub—and try another cable/port. For Ethernet, confirm the printer and PC are on the same network and the link lights are active.
• Driver/version conflicts: Remove old DCP-390CN and Brother Generic driver entries via Control Panel or Brother’s deletion tool, restart Windows, then install the latest Brother package and scanner driver together.
