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 interfer-
ence with other devices running at similar radio frequencies.
This limits the range of a Bluetooth device to about 10 meters
(about 32 feet).
Both the printer and the device it communicates with must
follow the Bluetooth standard.
Bluetooth Networking Overview
Each Bluetooth enabled RW series printer has a unique
Bluetooth Device Address (BDA) loaded into its radio module
when manufactured.
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 RW 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 Bluetooth are initi-
ated and processed without any operator intervention.
RW 420 printers can be equipped with both a Bluetooth
and an 802.11b radio, allowing communications with both
Bluetooth enabled devices and a Wireless Local Area Network
(WLAN) (see discussion below).
Wireless Local Area Network Overview
RW series printers can be equipped with several radio op-
tions which use the industry standard 802.11 WLAN protocol.

Other
terminals or communications devices may require the instal-
lation of special drivers to use the USB connection. Consult
your Zebra reseller or the factory for further details.
