Machines that prepare printed texts for photo-copies are being used a great deal today.Thousands of letters and figures of different sizes and thicknesses can now be arranged on a black glass disc that is only eight inches in diameter,to be printed in negative form(white on a black background).The disc on the machine turns constantly at the rate of ten revolutions a second.A beam of light from a stroboscopic lamp shines on the desired letters and figures for about two-millionths of a second.Then the image of the letters and figures section of film is large enough to hold the equivalent of a page of text.There is a keyboard in front of the machine that is similar to the keyboard of a typewriter,and the machine operator has only to strike the proper keys for the image of the corresponding letters to be immediately transferred to the film.The negetive image on the film can quickly be transferred onto paper.This method makes it as easy to reproduce photographs and illustrations as it is to reproduce the text itself.

复印机现在得到了广泛应用.成千上万不同大小和厚度的字母和数字,可以通过放在一块直径只有8英寸的黑色玻璃盘上,通过逆向模式（黑色背景上的白色）打印出来.玻璃盘的速率为每秒转10圈.从闪光灯发出一束光照在想复印的字母和数字上约百万分之二秒.接着这些字母和数字的映像可以调整到占满一张纸的大小.机器前有一个与打字机键盘相似的键盘,机器操作员只需敲一下正确的键,即可将相应的字母映像转化到底膜上,而底膜上的逆映象可以很快传输到纸上.由于是自动复制文本本身,这种方法使得照片和图表的复制变得非常容易.
