摘要
为了解决一般打印机或智能仪器中微型打印机在控制或检测的在线状态下,打印时其它功能暂停的现象,本文给出一个简单的设计并发打印程序的方法。该方法仅需最简单的查询式并行接口电路支持,采用功能于模块分层相对独立运行方式,实现打印机与其它外设的工作的并行性和连续性,从而可有效实现实时信息和报表的并发打印。
For the purpose of eliminating of the interrupt of other functions while the printers or mini-printers in intelligent devices is working under the on-line status of control and detection, this paper introduces a simple method to effectively realize simultaneous printing of real-time information and reports, which only needs support of a simple query-type papallel interface circuit to implement the parallel and continuous operation of both the printers and other peripherals.
