Thermal Printer_2022-11-22

Overview

After turning on the thermal printer, it will enter the standby state. The OLED will display the interface for selecting the print file. Then, you can select the file to be printed through 4 buttons, confirm, print, and transmit the content to be printed through the serial port and the microcontroller communication. Because it is controlled by a microcontroller, it is necessary to power the microcontroller and detect the printer's operating temperature. When it is working normally and in standby mode, LED1 will light up green. When the temperature of the printer is too high, LED2 will light up red.
The program source code and effect display are also in the project attachments. The oled display can be replaced according to the existing circuit^_^.
