Calalina - Brother Printer install - says installed but not showing in printer list.

My bad. There are installation instructions that appear after the download. In the past I just ran the installer and it showed up. You have to go into Printers and Scanners and follow the instructions pasted below, current as of 11-18-19.

For USB Users:

1. Connect the USB cable into your machine and your Macintosh. Ensure that the machine is powered on.
2. Note:
3. Do not connect the machine to a USB port on a keyboard or a non-powered USB hub.
4. The printer driver will be installed automatically.
5. You need to make sure if the installation of the printer driver is complete.
6. Select "System Preferences" from the Apple Menu.
7. Click the "Printers & Scanners (Print & Scan)" icon.

1. Check if your Brother machine is displayed in the "Printers" section.
2. If your Brother machine is displayed, the setup is now complete.
