Mostly printing just works on Mac. If not go to Settings (click the apple icon in the menu bar), Printers, and yet to manually add the printer. Macos usually grabs the driver's and everything for you.
If you're using a brother wireless and it acts weird with the mac, update the printer firmware. That usually resolves issues (it's very rare I have any issues though).
I've been a Mac user for 15 years and my printer is over 10 years old now but still works perfectly. It gives my wife's PC hell though...
