xerography (n.)

"photographic reduplication without liquid developers," 1948, from Greek xeros "dry" (see xerasia) + -ography as in photography. Related: Xerographic.

Xerography: Inkless printing and dry photography--named "xerography," from the Greek words for "dry" and "writing"--were recently demonstrated in the United States. Described as "revolutionary" by the New York Times, xerography employs static electricity to record images on special metal plates, and dry powders to reproduce the images on other surfaces. [U.S. Department of State "Air Bulletin," No. 79, vol. 2, Nov. 17, 1948]
