一、引言电子计算机的不断发展,对输出设备的要求越来越高,不仅要求能印刷字符(数字和文字)、绘图和印刷汉字,而且要求能够快速印刷。在目前常规的外部输出设备中,例如打印机、针形打字机、x-y绘图仪等还很难满足计算机发展的需要,静电印刷作为新型的快速输出设备目前是很适宜的。它的特点是:功能强,能快速输出,工作噪音小,结构简单,可靠性高。静电印刷使用的是特殊记录纸。 I. INTRODUCTION The continuous development of electronic computers and the ever increasing demands on output devices require not only printing of characters (numbers and words), drawing and printing of Chinese characters, but also the demand for fast printing. In the current conventional external output devices, such as printers, pin typewriters, x-y plotters, etc. are still difficult to meet the needs of computer development, electrostatic printing as a new type of rapid output device is currently very suitable. Its features are: powerful, fast output, low noise, simple structure, high reliability. Electrostatic printing using a special recording paper.
