Any communications port can transmit data from the host (Centronics,
RS232, Ethernet, and USB). Preliminary communications settings are
not required since the printer will automatically detect which port is
active.
Note: Never send data from 2 ports at the same time. Data cannot be sent
to more than one port simultaneously or data corruption and print errors
may occur.
