We have two computers (both Macs running OSX 10.9.5) and a multi-function printer (Brother DCP-7065DN) which we want both computer to use. The problem is that we only have two Ethernet connections available, so currently the printer is hooked up via USB to one of the Macs which the other one accesses via OSX's "printer sharing" feature. This works fine except for when the printer-attached Mac is turned off. I've heard about Ethernet cable splitters but get lots of conflicting information about what they can or can't do. So my question is if this would allow the printer to be attached to the network, or if I really need a third ethernet jack from a router?
