Where can I get a driver for Brother DCPT780DW, for USB printing?

I bought the printer as it has a USB connection. After running the Brother setup app, it prompts me to print via their limited app. No where on their website (that I can find) does it give you a place to download the driver. It advises Air Print. My Mac doesn't appear to have a compatible driver. Anyone have or know where I can get the driver for my M2Pro Mac Mini? Thanks
