Serial (RJ-11) Alternative Connector
The printer operates as a Data Communication Equipment (DCE) and those
printers with ethernet connectors also have an alternative serial RJ-11
interface used to connect to a Data Terminal Equipment (DTE) such as a
computer or terminal with a default configuration of 9600 baud, 8 bit data,
1 stop bit and No parity.
Note that looking into the printer's connector with the key notch pointing
down, pins are numbered from left to right.
