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.
