Compared to the MF4370dn, Canon imageCLASS MF4350d is having $50 cheaper price tag, only $249.99. Of course, the cheaper price tag must sacrifice something on it, you don’t able to attach this printer into your network as no Ethernet port available.
Don’t push a thing, when you don’t need it, right? As note, the MF3450d is equivalent in specs, ability and quality to MF4370dn, but, again, it doesn’t include Ethernet port.
