A printer cable is set up this way. (A crossover cable.)
RX is _always_ connected to a TX.
TX is _always_ connected to a RX.

An extension lead is set up this way. (A straight through cable.)
TX is _always_ connected to a TX.
RX is _always_ connected to a RX.

If you connect a Tx of one piece of equipment to a Tx on another piece of
equipment, you _never_ receive any data, because all transmitted (Tx) data
is _never_ connected to any receive (Rx) pins.
