摘要
通过对无线打印机连接器的设计与分析,提出了通用的并口信号串行传输打印通讯方案。利用8051实现并/串数据相互转换,并对控制信号、数据信号、状态信号进行重新帧格式设计。实际测试中,在8051串口波特率在2400bps时,对数据打印没有明显延时。
It provides a parallel printer communication method,which can send/receive control bus signal,data bus signal and status bus signal in sequence-signal.It gives the framework and designs new frame format,and it can distinguish the different signal from control bus signal,data bus signal and status bus signal.Through the test result,it has not delay when 8051 SC COM baud rate is 2400bps.
