Wireless Communications with Bluetooth™

Bluetooth is a worldwide standard for the exchange of data be-

tween two devices via radio frequencies. Bluetooth radios are

relatively low powered to help prevent interference with other de-

vices running at similar radio frequencies. This limits the range of a

Bluetooth device to about 10 meters (32 feet). Both the printer and

the device it communicates with must follow the Bluetooth standard.

Other than conditions specified elsewhere in this manual, only one of

the radio options can be installed in the printer at one time and the

antenna used for these transmitters must not be co-located or must

not operate in conjunction with any other antenna.

Bluetooth Networking Overview

Each Bluetooth enabled QLn320 printer is identified by a unique

Bluetooth Device Address (BDA). In order to exchange data, two

Bluetooth enabled devices must establish a connection.

Bluetooth software is always running in the background,

ready to respond to connection requests. One device (known

as the master or the client) must request a connection with an-

other. The second device (the slave or the server) then accepts

or rejects the connection. A Bluetooth enabled QLn320 print-

er will normally act as a slave creating a miniature network

with the terminal sometimes referred to as a “piconet”.

For the most part, communications using the Bluetooth pro-

tocol are initiated and processed without any operator inter-

vention.
