*1) Communication mode
It is possible to switch the communication mode setting between Bluetooth and USB.
Please see below for details to select the proper communication mode for your application.
Bluetooth : [Bluetooth] is printed when a self test is executed.
At the Bluetooth mode, the printer can communicate with an Android device,
Windows and an iOS device over Bluetooth.
Bluetooth (iAP) : [Bluetooth (iAP)] is printed when a self test is executed.
We recommend the use of this mode when the Auto Connection function is
ON and only iOS devices are used.
USB : [USB] is printed when a self test is executed. In the USB mode, USB
communication can be performed using the attached USB communication cable.
When you connect the serial cable, the printer is automatically switched to
USB communication from Bluetooth communication.
*2) Auto sleep function at iOS mode [Bluetooth(iAP)]
At iOS mode [Bluetooth(iAP)], set the Auto sleep mode to "NO USE" or Auto OFF mode.
When the printer wakes from the sleep mode, it cannot connect with the iOS device properly
due to the iOS specifications. Therefore, it is impossible to use the Auto sleep function when the
Communication mode of the printer is set to iOS mode [Bluetooth(iAP)].
 Simple method of switching over between Bluetooth (iAP) and Bluetooth communication modes
When performing the procedure to enter the memory switch setting mode (step 2 on page 15),
continuously hold down the POWER button and the FEED button even after the ERROR lamp flashes
five times until the buzzer sounds twice. The Bluetooth communication mode switches.
 Simple method of switching over between ESC/POS and Star Line emulation modes
1. Turn the printer power and open the printer cover.
2. Press and hold the POWER button and the FEED button simultaneously. As soon as the ERROR lamp
flashes five times, release the buttons. The emulation switchover takes place automatically.
3. After setting a paper, close the printer cover. The set emulation mode is printed out.
ESC/POS mode: EMU = ESC/POS Mode
Star Line mode: EMU = Star Line Mode
If the emulation mode is not switched correctly, repeat the above steps 1 to 3.
At that time, in step 2, make sure not to release the buttons until the lamp completes the 5th flash.
4. Please reboot the printer after switching the emulation between Star line and ESC/POS.
*It will be valid after rebooting the printer.
