现代的信息传播,要求快速地将数字信号进行硬拷贝,而激光打印技术的发展正是为了适应这种情况。七十年代中期,在阴极射线管系统打印技术成熟的情况下,1975年IBM公司推出了激光打印机产品,即IBM3800型激光打印机。此后的十年间,在美国和日本,激光打印技术得到了快速的发展,美国的IBM公司、Xerox公司等,以及日本的日立、富士通、日电等公司纷纷将激光打印机产品投入市场,使 Modern information dissemination requires the hard copy of digital signals quickly, and the development of laser printing technology is precisely to adapt to this situation. The mid-seventies, in the cathode ray tube system printing technology is mature, IBM introduced the 1975 laser printer products, IBM3800-type laser printer. The next ten years, in the United States and Japan, laser printing technology has been rapid development of the United States, IBM, Xerox, etc., as well as Japan’s Hitachi, Fujitsu, NEC and other companies have laser printer products to market, so that
