3 DTR Output Printer busy signal Number 6 & 8 pins (DSR, CTS)
5 GND －Ground Number 5 pin (GND)
[Terminal name explanations]
・TXD (Transmit Data)
Line for sending serial data from the printer to the host
When there is data flow control via x-ON/x-OFF: If the buffer reaches 8000 bytes
remaining while receiving data then DC3 (13H: Data receive disable signal) is output.
If the buffer reaches 8192 bytes remaining while receiving data then DC1 (11H: Data
receive enable signal) is output.
・RXD (Receive Data)
Line for sending serial data from the host to the printer. Framing error, overrun
When an error occurs the characters are distorted.
・DTR (Data Terminal Ready)
This is enabled when DTR/DSR flow control is selected.
When this signal is ready, data and commands can be written to the input buffer.
When this signal is busy, writing data causes an overrun error and the data is ignored.
The input buffer can be written to while printing. Busy may occur during self printing
when the power is turned on.
・GND (Signal Ground)
Signal line GND

5. Functions
5.1 Energy saving mode
Standard: As long as the power is not shut off with the power button, the power remains ON.
Power OFF mode: If there is no operation for a set time period, power automatically turns OFF. To
resume using, turn back ON as usual.
Power save mode: If there is no operation for a set time period, power save mode is automatically
entered into and the battery LED turns off. If the power ON button is pressed or 2
bytes of data are received (except via USB connection) the device returns to
print-ready status.
Even if there is no paper and the cover is open the device enters power OFF and power save modes.
Mode and time (1-99 min) settings can be made via Utilities.

・Power OFF: Less than approx. 6.1 V
5.3 Paper detection
・If there is no paper, the Error LED turns red and beeps intermittently.
・If paper running out is detected while printing, printing will stop. (Certain conditions excluded)
・If paper is replaced and the cover is closed, the Error LED turns off and stops beeping.
5.4 Cover open detection
・If the cover is opened, the Error LED turns red and beeps intermittently.
・If the cover is opened during printing, printing will stop.
・If the cover is closed, the Error LED turns off and stops beeping.
5.5 Head temperature detection
・If the head temperature reaches 65°C the head hot alarm stops printing and turns off the Power LED.
・If the head temperature falls below 60°C printing will automatically resume and the head hot alarm will be
released.
5.6 Non-volatile memory for saving logos
