摘要
以汽车客运站检票系统实时打印结算单的实际需要为背景 ,设计开发了打印任务的实时驱动与控制器 ,由一台计算机利用控制器就可驱动多台打印机的实时打印。该设计采用可编程逻辑器件 ,VHDL硬件描述语言为输入工具 ,接口简单 ,可靠性高 。
To satisfy the need of printing settling accounts in the checking ticket system,the timely driving and controlling device for the print task,which can drive several printers by one computer,is developed.The programmable logic device and VHDL is used as input tools,which have simple software interface,good reliability and practical value.
