Help Setting Up Ethernet-connected Brother Printer & Scanner

Continuing the discussion from Can't Access SSD as Secondary Storage:

@jamesfr can you explain what you’ve tried already and in what step you got stuck? Also have you read the community doc on this, yet? (doc: network printer)

Moving @51lieal’s reply here so we keep therads organized

Quoting from the other thread:

So you want connect to brother that attached to A network with your PC (qubes os) within B network right? for that case you should set up vpn on printer server and the PC (qubes os) connect to A network with vpn. It should work.
