8.2 Infrared (IR) Transmission
If your OM7212 is configured with the optional IR transceiver, it is capable of communicating via an IrDA 1.1 connection. To
determine if your printer is configured with an IR transceiver, print a test label as outlined in section 6 and look for the section
labeled “IR Port”.
8.2.1 Guidelines for IR Communication
�Turn the printer on.
�Place the host within 1 m (39 inches) of the printer’s IR port.
�Make sure the host’s transmitter/receiver is within a 15 degree angle from the center axis of the printer lens. Please
refer to the drawing below:

8.3 Bluetooth
If your OM7212 is configured with the optional Bluetooth radio, it is capable of communicating via the Bluetooth Serial Port
Profile (SPP). The Bluetooth SPP is a wireless serial port cable replacement connection. To determine if your printer is
configured with a Bluetooth radio, print a test label as outlined in section 6 and look for the section labeled “Bluetooth”.
8.3.1 Bluetooth Device Address (BD Address)
Each printer configured with the Bluetooth options, contains a unique address used to establish a Bluetooth connection. The BD
Address for each printer is printed on the test label under the Bluetooth section. Follow the instructions in section 6 to print a test
label.
8.3.2 Bluetooth Device Name (BD Name)
The Printers are configured with a friendly name to help identify the correct printer when making a Bluetooth connection. The BD
Name for each printer is OM7212 – nnnn where nnnn is the last four digits of the printer’s serial number. e.g. If the printer’s
serial number is 123456789, the BD Name will be OM7212 – 6789.
8.3.3 Maximum Simultaneous Connections
The OM7212 will allow only one Bluetooth SPP connection at a time.

8.3.4 PIN Code
Each Bluetooth enabled OM7212 contains a PIN code to help ensure you connect to the printer that you intend to. When
establishing a Bluetooth connection for the first time, you will be prompted by the host device to enter the PIN of the OM7212.
The PIN is the last four digits of the printer’s serial number. e.g. If the printer’s serial number is 123456789, the PIN will be 6789.
8.4 802.11b (Wireless Ethernet)
If your OM7212 is configured with the optional 802.11b wireless Ethernet radio component, the printer can be used in an
802.11b wireless network in a variety of configurations. Supported modes of operation include: Access Point (existing
infrastructure); Ad-hoc / peer-to-peer; 64 and 128 bit WEP encryption as well as unencrypted data transfer; Static and Dynamic
IP address allocation.
8.4.1 802.11b Configuration Description
This section describes the wireless network configuration process to allow the printer to participate on your new or existing
wireless network.
First, it is necessary to determine what network mode the printer will need to operate in. If there will be a wireless router or other
device acting as an Access Point (AP) on the intended wireless network, then the printer needs to be configured for AP mode. If
the intended network includes only workstations (such as a collection of laptop computers), or you do not currently have a
wireless network, then the printer needs to be configured for Ad-hoc mode. The mode can be altered as needed as the network
environment evolves.
Both modes require an SSID to identify the wireless network to all participants. In the case of an existing network, you will need
to set this to match the network’s SSID.
Additionally, the degree of encryption used needs to be determined as well. For existing networks, these settings must be
configured to match the intended network. If setting up a new network, the encryption settings can be configured as needed for
your purposes. These settings include Encryption Mode, at least one Encryption Key, and Use Encryption Key Entry.
Finally, if using Ad-hoc mode, the network channel needs to be set as well for the desired network (For AP mode, the channel is
automatically acquired from the AP during the connection negotiation process).
8.4.2 TCP/IP Protocol Configuration Description
All 802.1 1b wireless Ethernet communications utilize the TCP/IP protocol suite for operation on the network.
The printer uses TCP port 9100 for raw data transfer.
If your network will have a DHCP-enabled server or router on it (most wireless routers can be configured to provide DHCP
services), the simplest and most flexible configuration available for the printer is to enable dynamic IP Address Allocation via
DHCP. If there is no DHCP server available, or you have a need for a statically assigned
