一、计算机与打印机接口部分接口部分是打印机中比较容易发生故障的部分,这通常是由于用户带电拔插打印机和计算机相连的通信电缆造成的。发生此类故障时,应先判断故障是在主机一边还是在打印机一边。采用故障分离法判断,方法是:(1)用DOS引导盘计算机,按屏幕硬拷贝键(Print Screen),如果能打印出西文,说明打印机接口和主机打印口正常,问题出在操作系统,进行杀毒或检查操作系统后故障可排除。(2)如果上述方法仍不能使用打印机打印,可将打印机的通信电缆接到另外一台
First, the computer and printer interface Some of the printer interface is part of the more prone to failure, which is usually due to the user plugged and unplugged printer and computer connected to the communication cable. When such a fault occurs, you should first determine whether the fault is on the host side or the printer side. The use of fault separation method to judge, the method is: (1) DOS boot disk computer, press the screen hard copy button (Print Screen), if you can print in Spanish, the printer interface and the host printer port is normal, the problem lies in the operating system Antivirus or check the operating system after the failure can be ruled out. (2) If the above method still can not use the printer to print, connect the printer’s communication cable to another
