Bluetooth Pairing and Printing

(only valid for printers with Bluetooth)
Bluetooth pri nter needs to be paired with the main device driving the printer before working, and the pairing process is initiated by the main device.

The general pairing method is as follows:

1. Turn on the printer.
2. The main device searches for external Bluetooth device.
3. If there are multiple external Bluetooth device, select the printer corresponding to BDA address.
4. Enter the initial password "0000" or "1234".
5. Complete the pairing.

Please refer to the Bluetooth function description of the main device for the specific pairing method. VVhen pairing, the label printer with Bluetooth interface must be on.

Note: During pairing, please do not turn on multiple printers at the same time, otherwise you may not be able to judge which printer was successfully paired.

After successful pairing, other host computers can still be paired with the printer, and each printer can be paired With up to 8 host computers. If more upper computers are paired with printers, the host computer paired with the printer at the earliest will be automatically removed from the pairing list by the printer. At this time, if this host computer needs to drive the printer for printing, it needs to be paired again.
(For multi-connected Bluetooth only.)

Use Bluetooth Interface for Printing

(only valid for the printers with Bluetooth)

For host computers with virtual Bluetooth serial ports (such as mobile phones using SMARTPHONE, POCKET PC, PALM, notebook computer, etc.), after successful pairing, printing data can be sent to the printer via the virtual Bluetooth serial port for printing. If the host computer does not have a virtual Bluetooth serial port, when you want to drive the printer for printing, please consult the supplier of the host computer.

The Switch, Key and Indicator Light of Printer

Precautions for power switch/use

1. Turn the printer power switch to on (1) state, and the printer will be turned on,
2. Turn the printer power switch to on (O) state, and the printer will be turned off.
3. Turn off the printer with power switch. If you pull the power plug directly, it is easy to damage the internal circuit of the printer and cause print data loss.
4. After power-off, wait for a while (not more than 5 seconds) before turning on the printer again otherwise it is likely to cause a failure.
5. Please use the original battery of this machine, otherwise it may lead low print quality or damage to the printer.

Attention:
Make sure the power supply is connected before turning on the printer.

Label Learning

Note: In the following cases, the user can perform label positioning learning so that the printer can better position the label:

• Install and use the printer for the first time.
• First use of printer after sensor cleaning.
• Reuse the printer after it is not used for long time.
• Replace with a new type of paper roll.
• The printer cannot recognize the mark effectively during printing.

When the printer is ready, press and hold the FEED button for 3s until the standby status indicator flashes twice, release the button, and the printer will start learning and feed paper. If the printer learns under continuous paper mode, the learning is invalid.
Users can also complete the learning through the printer tool software. (refer to "Instruction for Printer Setting Tool". )

Note: After learning, you can re-open the top cover and place the blank label paper just fed during learning back for printing to avoid paper waste.
