QLn Series User Guide

Wireless Communications with Bluetooth™

Bluetooth is a worldwide standard for the exchange of data 

between two devices via radio frequencies. Bluetooth radios 
are relatively low powered to help prevent interference with 
other devices 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 fol-
low 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 and QLn220 printer is iden-

tified 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 QLn Series 
printer will normally act as a slave creating a miniature net-
work 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.
