引言 早在七十年代初,人们就一再对系统输出设备新系列的设计提出要求,对任何已知字符的样式和尺寸应该基本上能任意变换。此外,还要求打印质量高、噪声低、可靠性高。因此探索了把字符和数字分解为点阵的非击打式印刷技术。更确切地说,探索了应用激光曝光的电摄影技术。它似乎有着良好的发展前途。这种技术能形成高分辨力的点阵,并且它的噪音较低,操作可靠。最主要的是它只要使用未经处理的普通纸,因为在数据处理和字处理应用方面都已使用这种纸。 Introduction As early as the early 1970s, people repeatedly demanded the design of a new series of system output devices. The style and size of any known character should be essentially arbitrary. In addition, it requires high print quality, low noise and high reliability. So I explored non-impact printing technology that breaks down characters and numbers into bitmaps. More specifically, the electrophotographic technique using laser exposure was explored. It seems to have a good future for development. This technique creates a high-resolution lattice with low noise and reliable operation. The main thing is that it uses plain paper as it has been used for both data processing and word processing applications.
