The Design And Implementation Of A Thermal Printer System Based On ARM

Thermal sensitive printing technology is mature and stable, widely used. The existingthermal sensitive printer products cannot fully meet user customized printing demand,because manufacturers hardly provide the original code and development interface, besides,the optional communication way with upper monitor is less. The situation above greatlylimits the convenience, freedom and friendliness of thermal sensitive printing technology. Sodesigning a complete set of thermal sensitive printer system has practical significance. Thissubject does fully comprehensive analysis and research to a complete set of thermal sensitiveprinter system through its software, hardware and function.This subject deeply research the design and realization of thermal sensitive printerrelated hardware, including optimization of control circuit on ARM platform, interface circuitof external device communication, optimization of core driving circuit of thermal sensitiveprinter, etc. According to system functional requirements, this subject further research thedesign and realization of thermal sensitive printer related software combining with the featherof hardware circuit, including low-layer serial communication protocol, SPI communicationmodule, data processing module, printing control module, etc. The print control modulecontains functions for heating delay, synchronous motor control, paper detection, temperaturedetection, etc. This subject realize the printing control method of thermal sensitive printer onARM platform which can be used to customize thermal sensitive print service and othersystem, for example, embedding this system to mobile terminal, multi-communicationprotocol compatible, special control of barcode print format.The design and realization of thermal sensitive print system on ARM platform achievesthe printing effect of existing thermal sensitive printer products. The technology of hardwaredesign and the core code of software design are applicable to develop customization printerproducts combining with the design of communication protocol and driving programaccording to actually requirements.
