Shouldn’t matter... try using Bonjour... printer should be turned on... it’s a USB printer...Brother sez, with Big Sur (mac os 11, if your machine supports it, use AirPrint...the iPrint and scan app mentioned is for mobile devices ONLY, eg iphone, ipad, kindle fire, windows phone, Android and BlackBerry..0
anyways-HERE is the printer driver for mac os 11>>>>>👀

use that... please note. This is a usb printer...so connect it up to your mac via USB 2.0 ( standard usb 2.0 B to A printer cable will work fine... airprint only works if it’s setup on your Mac and for that you need to make sure wifi is turned on and then do the bonjour thing... and add printer via IP... man alive this is getting mighty complicated !!! Usually under system prefs>>> print/print, fax>>> you would go to add a printer, and make sure at the top right of the add a printer screen, it’s set to USB... then click the plus button... the name of the little rascal should show up, eg, Brother -HLL 2320D, then U click on “OK”... to reset printing system on any mac... go to print window, where U see the printer... any pending jobs, status, etc... you should see a big [+] and a big [ - ] button. Using the mouse/trackpad, move the cursor (the arrow,) over to the [+] button. hold down either the Shift button or the Option button on your keyboard while clicking on the [+] with your mouse at the same time... you should see “reset printing system”. Say “OK” to that...
and let’s see about Gutenprint, shall we???... oh, i am surprised.! .. i thought it would install and work well in Catalina (10.15) and up... apparently it’s iffy... catalina breaks support for anything 32 bit at all... it has to be 64 bit or it won’t run at all... oh rats... anyways... i’ve beaten this dead horse enough... y’all making my brain hurt, so i’m a-leaving
