Connecting the Printer
Data Reception Methods
The printer provides two interfaces for receiving print data and other information: the
serial port and the infrared port (optical interface). The interface selection automatically
switches according to whether or not the RS-232C cable is connected to the serial port.
Data is transferred through the serial port only if the RS-232C cable is connected before
the printer is turned on.

Direct the printer's infrared port straight at the port of device to be
linked.
• Transmission can be achieved within a 15˚ angle horizontally and vertically from center.
• Confirm that there are no obstacles in the space between the printer and the device
to be connected. Data cannot be transmitted correctly if any obstructions are
present in this space.

• Data may not be received correctly when transmitted in direct sunlight,
under fluorescent lamps, and in other areas with strong light.
• Data may not be received correctly after the printer has been left for an
extended period in temperatures outside the recommended storage
temperature range.
• Transmission distance varies according to the device used and the surround-
ing conditions, so it may be impossible to establish a connection within the
connection range provided in the specifications. There are devices that
cannot be connected within 10 cm (0.33 feet) of the light receiver.
• A communication error may occur if it is used connected to another
infrared device.
