文章通过对打印机接口工作时序的分析 ,讨论了用PC的增强型并行口模拟打印机的工作时序 ,使CELL 6 10型血常规分析仪的Centronics标准并行打印口认为与其通信的是一台真实的打印机 ,从而实现了数据的自动采集 ,给出了增强型并行口数据采集的应用实例。
The article analyzes the working sequence of the printer interface and discusses the working sequence of the PC with the enhanced parallel port analog printer. The Centronics standard parallel printer port of the CELL 6 10 blood analyzer is considered to be a real printer , So as to realize the automatic data acquisition, and gives an application example of enhanced parallel port data acquisition.
