Geehy Diversified Thermal Printer Solutions Meet Differentiated Printing Needs

PublishTime： 2023-05-14 Article Source：Geehy Semiconductor News

A semiconductor heating element is installed on the print head to control the heating element on the printer core. After receiving the print data, the thermal printer converts the print data into bitmap data, and after the print head is heated and contacted with the thermal printing paper, it can print out the required pattern and text.

Classification of Thermal Printers

According to the arrangement of their thermal elements:

Thermal Serial Dot System: Columnar thermal is an early product and is mainly used in some applications where the printing speed is not high.

Thermal Line Dot System: Line heat is a technology of the 1990s, and its printing speed is much faster than that of column heat, and the fastest speed has reached 350mm/sec.

To achieve high-speed thermal-sensitive printing, besides selecting a high-speed thermal-sensitive printing head, the corresponding control board must be matched with it.

Geehy 2/3/4-Inch Thermal Printer Solution

It is mainly composed of a control circuit, stepper motor driver, thermal film, human-machine interaction, and peripheral circuit. The MCU in the control circuit is used to dynamically process the image characters and control the peripheral devices. The MCU receives the print command and subsequently sends the dot matrix data to the print head through the SPI interface to complete the data conversion while detecting the print head temperature and controlling the stepper motor for precise paper rolling key presses, and other operations.

GW3323 2-Inch Bluetooth Thermal Label Printer Solution

As one chip can realize Bluetooth phone pairing and thermal printer control, the solution is very cost-effective and can be used for labeling groceries, household items, and cables. With rich interfaces and reliable transmission, the master chip can effectively guarantee stable output and no need for multiple serial interrupt services. The ADC determines whether overheat protection is needed by detecting the thermistor value and whether the paper is running out by detecting the optocoupler output.
