GY-NQB301

80MM embedded thermal printing module

This is an embedded label printer specially developed for various SCM/Android system/computer terminal control applications in industrial manufacturing and intelligent weighing scales. It is small in size, stable in performance and strong in scalability.

Specification parameters：24V-3A

communication interface:RS232/TTL+USB+485 interface

Printing type:Three types of printing: receipt, label, and black label paper

Secondary development:Supports controlling printing on Linux, Android, PLc, Raspberry Pi, Windows, microcontrollers, and more

: 80MM embedded thermal printing module

This is an 80MM built-in thermal printing module for a self-service queuing and calling machine. It does not require carbon tape, ink, or color bands, and thermal technology printing. It has fast printing speed, saves you every minute and second, clear printing, and a large paper compartment, eliminating the need for frequent paper changes.

: 80MM embedded thermal printing module

It can print receipts/label paper/black logo printing, and the three printing modes aremore widely used.Supports secondary development ofmicrocontrollers/Android/Windows/Raspberry Pi/touch screen/PLC, supportsUSB/RS232+LAN interface, and supports 24V-3A power supply printing.

Common Problem

How to connect the serial port of the printer?

All of our integrated printers (products that need to be integrated into the device) have a232serial port or TTL serial port with 4 pins, defined as TX, RX, GND, and DTR. Currentlytheactual amount of data printed is not large, usually using 3 lines, which are TX, RX. andGND
After using the printer for a period of time, it may not print clearly. ls there no ink left?

No, this type of thermosensitive printer does not require consumables such as ink, toner.orribbons. The color development principle relies on the printer's movement heating to makethethermosensitive paper, and the color development agent on top of it produces the colorthatwe see as a small ticket. The reason for unclear printing of thermal printers is mostlyrelatedto the thermal color agent coating of thermal paper. However, cheap thermal paper onthemarket has poor thermal color agent, resulting in blurry printing and short retention time
What is the situation of unclear printing effect?

1. First, troubleshoot the issue with the printer itself. Open the paper compartment coverandcheck for dirt on the rollers and print head. lf not, troubleshoot the issue. lf so, gently cleanitup! 2. Check if there is moisture on the paper roll. lf not, it can also be ruled out! 3. it's justthatthe current of the power supply is not enough, and there is a possibility of virtual
Do l need to install a driver when printing via USB on a computer?

lf necessary, you can control printing through the USB on the computer side. You need toinstall a printer driver, and then call the original driver to print when the software controls, justlike the principle of calling the local laser printer or inkjet printer after the WORD is edited!Using driver printing, there is no need to worry about the printer's instruction manual, but
