IR Communications
Printers equipped for infrared (IR) communications are identified
by a small “IR” logo on the unit’s label. IR allows wireless commu-
nications between the printer and the host terminal. IR units can
also communicate with a cable as detailed above, however, IR
functions are disabled when the cable is plugged in. QL 320 units
with the IR option can be configured to conform to the standard
IrDA communications protocol
Linking a Printer to an IrDA Host
IrDA compliant terminals will automatically initiate communica-
tions to the printer. First insure that there is a direct line of sight
between the printer and the terminal that will be sending data. The
IR window on the front of the QL 320 must face the corresponding
window on the terminal to properly send and receive signals. An
IrDA compliant terminal will seek out any linkable devices and es-
tablish communications between them, even turning the printer on
if necessary.
