Question about Brother MFC-J5740DW

Hello all I definitely need help in choosing an A3/A4 printer: The criteria would be: Absolutely with LAN port so I can connect it to the router. I have an older Powerbook with the operating system MacOS High Sierra 10.13.6, so it should be compatible in this respect. Colour and b/w Whether laser or inkjet doesn't matter, but price segment under Fr. 1000. I am a one-woman business and do not print in bulk, nor do I need a super print speed. I do print regularly, but moderately in number, I need it alone. Duplex would be oool, but not first priority. No "giant furniture" à la professional company printer. Can anyone help me? I'm a bit "lost in space" and infinitely grateful for tips. Kind regards
