一、引言我们在分析总结国产CY160-5,CY160-6与CYD-1203等几种型号宽行字符打印机的优缺点的基础上,吸取了利用微处理机控制点阵打字机的成功经验,设计了一个微处理机控制的低噪声宽行字符打印机控制器,用它来控制一台打印速度为600行/分,字符种类为96字、行宽为136位、走纸时间为25毫秒的低噪声宽行打印机,取得了满意的效果,使宽行打印机的性能和质量都得到了进一步的提高。
I. INTRODUCTION On the basis of analyzing and summarizing the advantages and disadvantages of several models of wide-line character printers such as domestic CY160-5, CY160-6 and CYD-1203, we draw on the successful experience of using microprocessor to control dot matrix typewriters and designed A microprocessor-controlled, low-noise, wide-line character printer controller for controlling a low noise print speed of 600 lines per minute, 96 characters of characters, 136 bits of line width and 25 milliseconds of paper feed time Wide line printers, has achieved satisfactory results, so that the performance and quality of wide line printers have been further improved.
