The first laser printer
was demonstrated in 1969
. An engineer
named Gary Starkweather, who was working at the Xerox Palo Alto Research Center
, figured out a way to combine a laser and Xerox
's tried and true xerography
process. This process allowed for a printer that could print graphics type rather than just fixed-width
And now for some technical geeky stuff:
Now, regular xerography works like this: A photo-sensitive drum is charged with electrons, and then an image of the paper you want to produce is reflected on it, then ink is put on the drum, the paper is put on the drum, and then the paper is fused by putting it over a heated roller.
Now, with a laser printer, instead of reflecting an image onto the the drum, a high-intensity laser beam is used. A mirror that spins at high speed, spreads the beam out so that it can write the image onto the drum quickly.
