基于STM32的微型热敏打印机的设计和实现

基于STM32的微型热敏打印机控制系统以STM32F103C8单片机为控制器,以存储器、步进电机和热敏打印头为控制对象,上位机和单片机之间进行串口通信,串口调试软件发送命令和字符,就可以在热敏纸上直接打印相应的字符。该文阐述了系统的硬件组成及软件的实现过程,并给出系统测试结果。测试结果表明,该微型热敏打印机控制系统稳定可靠,打印字迹清晰,不仅可以打印英文、汉字,还可以打印条形码和二维码等。

Design and implementation of the micro thermal printer based on the STM32

Based on STM32 , micro thermal printer control system puts STM32 F103 C8 microcon-troller as controller, storage, stepper motor and the thermal print head as control object, the serial com-munication between PC and single chip microcomputer, a serial port debug software to send commands and characters, can print directly on the thermal paper corresponding characters. This paper expounds the hardware and software of the system implementation process, and system test results is given. Test re-sults show that the micro thermal printer control system is stable and reliable, clear printing, not only can print English, Chinese characters, but also print bar codes and QR code, etc.
