By mocheeze ·
why won't a cross over cable work when hooking up a printer to a ethernet port from wall outlet?

i know basic but i figured out that a network printer was not working cause of this, but just don't know why.

Assuming that there is a switch or router between the PC and the printer, the network port on the printer acts just like any other network device.

I guess that the wall socket terminates in a patch panel. The crossing over is done here so you do not need the cross over cable to the printer.

Here is the answer you are looking for:

A printer is an end node device and only require a strait through connection to the hub/switch. When you wire a buiding into a patch panel to connect from a patch panel to the switch all you use is a patch cord same principal for the other end. The only time you need a cross over is from PC to PC, Switch to Switch but from end node device such as a laptop, PC, Printer that is not required only a regular patch cord.

Now some switches offer auto uplink which means if it is a cross over cable it and needs to be a patch cord it will switch it in the port and same goes for a regular patch cord.

But for good rule of thumb always cross over and patch from the wire level "Layer 1" instead of doing it at the switch

A straight cable transmits on pins 1 & 2, it receives on pins 3 & 6. This is the same on both ends of the cable.

The hubs, swithches, routers, ect do the pass from transmit to receive.

A crossover cable swaps the transmit and receive on one end of the cable, ie crossover.
