Cable Communications
CAUTION. The power should be turned off before
connecting or disconnecting the communications cable.
All QL 320 printers can communicate by cable; the specific ca-
ble supplied with your printer will vary with the host terminal. The
8- pin circular connector on your communications cable plugs
into the serial communications port on the side of the QL 320
printer. It is keyed to assure correct alignment; do not try to force
it if it does not plug in. The other end of the cable must be
plugged into the host terminal as shown in Figure 10, or to a seri-
al port on a computer (Figure 11.) Communications between the
terminal and the printer are controlled by the applications running
on the terminal and the printer.
