Different solutions for Brother Printer Driver Unavailable
Here are a couple of methods you can try when the brother printer driver is unavailable on your system.
Reinstallation - The first thing that crosses your mind should be the reinstallation of the driver. Use these steps for that:
After that, you need to wait for at least 10 minutes and then plug in the printer back again. Now, go to the Devices and Printers once again and set the Printer as the Default device for printing.
New Driver Installation - Once the old driver is uninstalled from the system, you need to install a new driver.
Then, you need to select the OS family, hit OK, and then get the latest driver in the Firmware section.
Update the OS - You can also try to update the OS to get the latest drivers for any hardware installed on your system. Windows 10 generally updates all the drivers installed on the system with the windows update. So, you don't need to uninstall and reinstall the drivers on your computer manually.
