Notes:
1. The printing speed has been measured under the following conditions;
• Printing Kanji with 16-dot mode character and space is not allowed between lines.
• One pry roll paper is used.
• The battery pack is fully charged before printing.
2. The communication range can be varied depending on the surrounding environment.
3. IT-3100M55E, IT-3100M55E-CN, IT-3100M55U, IT-3100M56E, IT-3100M56E-CN and
IT-3100M56U do not integrate the serial interface.
4. A partner device connected to this interface must output data in the RS-232C signal level when
communicating with the terminal.
