Try resetting the print system and re-installing the printer. To reset the printing system, go to System Settings -> Printers and Scanners -> Right-click the printer and you'll see the option to reset the printing system.

Then re-add the printer. It should support Airprint with no installed driver.
You can find the support page for this printer here:

There's a recent firmware update and you can install the drivers but Brother recommends using Airprint.
