随着计算机技术的发展和推广使用,我国在发展煤矿机械化的基础上,又大力发展以计算机为信息处理中心设备的煤矿监控技术。而TP801—Z80单板机由于价格便宜,普及率较高,在煤矿生产过程控制,数据采取和处理中多被采用。但与其直接配接使用的TP801P或TPμP打印机,均属微型打印机,其纸宽为58mm,每行仅可打印 5×7点阵字符32个,无法将较多的监控参数实现汉字报表打印。我们将TP801与CP—80宽行打印机配接,除可打印各种字符、图符、图表、曲线外,还可方便的用中文印字制表,收到满意的效果。 一、打印机接口简介 CP—80TYPEⅠ型打印机采用RS—232C接口与系统相连。它的最大数据传送速率为400波特/秒;同步信号依靠外部提供STROBE
With the development and popularization of computer technology, on the basis of developing coal mine mechanization, our country also vigorously develops the coal mine monitoring and control technology which takes the computer as the information processing center equipment. The TP801-Z80 single board machine because of cheap, high penetration rate, in the coal production process control, data acquisition and processing are used more. However, the TP801P or TPμP printers used directly with the printers are micro-printers with a paper width of 58mm and can print only 5 × 7 dot-matrix characters per line. Therefore, more monitoring parameters can not be printed in Chinese characters. We will TP801 and CP-80 wide-line printer with access, in addition to printing a variety of characters, icons, charts, curves, but also easy to use Chinese printing table, received satisfactory results. First, the printer interface profile CP-80TYPE Ⅰ type printer using RS-232C interface with the system. Its maximum data transfer rate is 400 baud / sec; synchronization signals rely on external STROBE
