Avoid blocking between the printer and the device to be connected.
Otherwise, data may not be sent correctly.
CAUTION!
• Communication in a place exposed to strong light such as direct sunlight and
fluorescent lighting may fail in receiving correct data.
• Communication may fail in receiving correct data after leaving the printer
unused for a long time in other than storage temperature.
