Baud rate: 2400pbs to 115200pbs (Users can get the current transfer rate from the printer self-test page.)

Data word length: 8 bits

Stop bit: 1bit

Parity: None

Serial cable: We made the special cable using a mini port like the Mini USB port that connects the printer. The following figure shows the meaning of the pins at the RS-232 Serial Interface:

The connection between the printer and the host follows the following rules:









However, the printer typically only works when receiving the data, nothing should respond to the host, then the TXD signal can be ignored and then the connection can be downloaded as follows:







4-2. Bluetooth connection

Bluetooth is a patented standard for technology not used for short-range data exchange (using short-range radio transmissions in the ISM band at 2400-2480 MHz) from fixed devices and mobile, by creating personal networks (PANs).

4-2-1. Bluetooth specifications

Using the blue-core 4-Ext chipset, fully compatible with Bluetooth 2.0;

Reception signal has high sensitivity, low size, low consumption

Supports a wide variety of baud-rates: 1200bps ~ 1382400bps;

Supports the SPP standard, the maximum transfer speed is up to 3Mbit/s;

4-2-2. Use the "AT" command to change the Bluetooth Module parameters

Note: The following changes can not be made by the user, they should be done at the factory by the manufacturer. So if the user wants to change these parameters, please inform the store before ordering our printers.

Edit the name - Send the character string "AT + NAMEXXXX", the result being "Okname", for example if you want to change the name to "LY58", send "AT + NAMELY58"

Edit the PIN code --- Send the character string "AT + PINXXXX", the result being "Oksetpin", for example if you want to change the PIN to "8888", send the string "AT + PIN8888" (Note: The default PIN is "1234", you can only reset your PIN to four digits.)

Delete the Bluetooth address --- Send the string "AT + CLR00", the result being "Okclear";

Change the baud rate --- Send the character string "AT + BAUDX, the result being "Ok + current baud rate ";

X represents the transfer rate code as follows:





























For example, if you want to change the baud rate to 115200 bps, send the string "AT + BAUD8".

4-2-3. Making the connection.

1. Turn on the printer;

2. Search Bluetooth device with host device;

3. If there are other Bluetooth devices, select the printer "LY58" (for example);

4. Enter the default match code "1234"

5. Pairing succeeds.

4-3. USB interface

The printer is connected via standard Mini USB cable (included in accessories) for communication. The USB type belongs to the slave device type.


Make sure the printer is turned on and the USB cable connects to your computer for the first time. If we do not find "USB001", check if you can find "USB Print Support" at the location below: Path: My Computer - Properties - Management - Universal Serial Bus Controller), otherwise check the connection of the cable and printer.

5. Installing the roll of paper

The printer uses 58 mm thermal paper and has a lightweight paper loading. So the paper is easy to install. Paper max diameter is 50mm.

The method of installing thermal paper is as follows:
