2.3 Connecting to a Host
Ensure that the Power Switch is OFF when making printer connections.
The printer can be interfaced to a host via the parallel, serial, Ethernet and USB ports. (Ethernet
users, consult the documentation that accompanied the option.) Following power-up (or after a
period of inactivity), interface port selection occurs automatically upon detection of valid data. If
the incoming data flow stops and the Host Timeout period (see Section 4.2.5) is achieved, partially
received formats will be ignored and the port detection process repeated.
