Brother MFC-420CN USB Printer Driver

The Brother MFC-420CN USB Printer driver lets Windows communicate with your printer so you can send documents and access supported print settings. It is useful when setting up the printer over USB, reinstalling Windows, or troubleshooting a missing printer or failed print jobs.

Key Features

• USB printing support: Enables communication between the Brother MFC-420CN and a compatible Windows computer.
• Print controls: Provides access to supported settings such as paper size, orientation, and print quality.
• Windows compatibility: Driver options cover Windows 10, 8.1, 7, Vista, and XP; choose a package that matches your operating system and architecture.
• Printing setup: Helps Windows identify the correct printer model rather than relying on an unsuitable generic driver. Scanning and other multifunction features may require separate software.

How to Install Brother MFC-420CN USB Printer Driver

1. Check your Windows version. Confirm your operating system and whether it is 32-bit or 64-bit before starting the Brother MFC-420CN USB Printer driver download for Windows. If you are comparing Windows 10/11 compatibility, note that Windows 11 is not included in the supported OS list provided here.
2. Choose the correct package. Select the latest version available for your specific Windows release, not simply the newest package overall. Use a trusted free download source and verify that the driver lists the MFC-420CN.
3. Prepare the printer. Turn it on and close open applications. If using an installer, leave the USB cable disconnected until the setup instructions tell you to connect it.
4. Install the driver. Run the downloaded installer and follow its prompts. If the package contains only driver files, extract them and use Windows’ Add Printer wizard to select the supplied driver.
5. Connect and test. Attach the USB cable when prompted, finish setup, and print a test page. Restart Windows if requested. If printing fails, check the cable, selected printer, and print queue.

Keep the driver updated by checking periodically for a compatible release, especially after Windows changes or recurring printing problems. Before you update, confirm that the replacement supports both your printer and operating system. For this older model, the latest version may still be a legacy driver; avoid replacing a working installation with an unverified package.
