摘要
介绍了基于89S51单片机的微型热敏打印机的组成,分析了打印原理,详细给出了整体流程以及各个功能模块的软件设计。热敏打印头采用I/O口模拟串行数据传输实现数据加载。设计的微型热敏打印机运用于实际,取得了良好的效果。
The constitution of micro-thermal printer based on 89S51 single-chip microcomputer is introduced. The print principle of micro-thermal printer is described. For the thermal head, the whole flow and the software design of each function module are given in detail. The data are loaded through simulating serial data transmission by I/O interface. The designed micro-thermal printer is put into practice, and the effect is well.
