How Laser Printers First Appeared and Developed

by Stargaser
On October 22, 1938, when American inventor Chester Carlson together with German immigrant Otto Kornei first transferred an image from a glass microscope slide to a sheet of wax paper using method later called electrophotography. Kornei wrote the words “10.-22.-38 ASTORIA.” in ink on a glass microscope slide. Then the experimentalists prepared a zinc plate with a sulphur coating, darkened the room, rubbed the sulphur surface with a handkerchief to apply an electrostatic charge. After that they laid the slide on the zinc plate, exposing it to a bright, incandescent light.

Web Friendly Printer

by Stargaser
If you ever tried printing a random web page, you probably know that what you get is far from original. There are stripes of white space, images chopped in two, text cut from one side, and so on. That’s annoying. On the other hand, with the development of Internet era people tend to print less, partially because of such web-hostile printer behavior.
