This is a super quick page because I'm adding printers now so wanted to put some notes down.
To add the printer in Matt's office: https://www.youtube.com/watch?v=aV9PLmeUJl4&feature=youtu.be (on a Mac, open Printers & Scanners, click the + to add a printer, select the only printer that starts with "Brother")
To add the CB3 Level B printer: open Printers & Scanners, click the + to add a printer, select the printer called CB3 Level B Canon iR-ADV C2230 @ CB3-F5KMM0HDF694
