前言利用激光束印刷文件的激光打印机,其商品化工作十分活跃。随着用计算机编辑印制书刊的台式电子出版的普及,以及从半导体激光器到所有零部件价格的下降,激光打印机本身的价格便大幅度下降,原本具有的低噪声、高速和高分辨率等特征便受到人们的重视,预计其需求量也会大大增加。激光打印机概要激光打印机的原理,基本上与复印机相间。复印机是将光投射到原稿上,通过透镜将 Introduction Laser printers that use laser beams to print documents are very active in commercialization. With the popularity of desktop electronic publishing for editing printed books and publications and the decline in the prices of all components and parts from semiconductor lasers, the price of laser printers has been drastically reduced, with features such as low noise, high speed, and high resolution. Due to people’s attention, it is expected that the demand will increase greatly. Overview of Laser Printers The principle of a laser printer is basically that of a copy machine. The copying machine projects light onto the original, through the lens
