Cable Communications
CAUTION. The power should be turned off before connecting
or disconnecting the communications cable.
All QL Series printers can communicate by cable; the specif-
ic cable supplied with your printer will vary with the host ter-
minal. The 8- pin circular connector on your communications
cable plugs into the serial communications port on the side of
the printer. The connector is keyed to assure correct align-
ment; do not try to force the cable if it does not plug in. The
other end of the cable must be plugged into the host terminal
as shown in Figure 11, or to a serial port on a computer (Fig-
ure 12.) Communications between the terminal and the print-
er are controlled by the applications running on the terminal
and the printer.
