• It supports the XML print function (ePOS-Print) via HTTP/HTTPS communication.
• It is equipped with a CPU low-power consumption mode.
• It supports IEEE802.3az (Energy Efficient Ethernet: EEE).
What is the CPU low-power consumption mode?
If there is no data transmission or receiving and the push button is not operated for 3 seconds
or longer, the UB-E04 transitions to CPU low-power consumption mode. While in CPU low-
power consumption mode, the UB-E04 uses less power than usual. You cannot disable the
CPU low-power consumption mode function.
To use the EEE power-reducing function, you must have a computer that supports EEE
available.
