LQ1600K打印机接口故障的处理方法

Dealing with LQ1600K Printer Interface Failure

论述了LQ16 0 0K打印机联机后 ,不能正常打印数据的故障处理方法 ,介绍打印机接口芯片的结构原理以及与外围电路的通信原理 ,用实例介绍了故障测试技术、排除方法及防范措施。

This paper describes the ways to deal with failure-the printer LQ1600K can′t normally print data after it is on line, then it presents structure of printer interface chipware and communication principle between the printer and peripheral device, at last introduces failure testing technology, elimination method and protection measures in an example.
