Gary Keith Starkweather (January 9, 1938 – December 26, 2019) [ 1 ] was an American engineer who invented the laser printer and color management. Starkweather received a B.S. in physics from Michigan State University in 1960 and an M.S. in optics from the University of Rochester in 1966. In 1969, Starkweather invented the laser printer at the ...
The laser printer was invented at Xerox PARC in the 1970s. Laser printers were introduced for the office and then home markets in subsequent years by IBM, Canon, Xerox, Apple, Hewlett-Packard and many others. Over the decades, quality and speed have increased as prices have decreased, and the once cutting-edge printing devices are now ubiquitous.
The first color photograph made by the three-color method suggested by James Clerk Maxwellin 1855, taken in 1861 by Thomas Sutton. The subject is a colored ribbon, usually described as a tartanribbon. Colour photographyis photographythat uses media capable of capturing and reproducing colors. By contrast, black-and-whiteor gray-monochrome ...
The laser printer, based on a modified xerographic copier, was invented at Xerox in 1969 by researcher Gary Starkweather, who had a fully functional networked printer system working by 1971. [125] [126] Laser printing eventually became a multibillion-dollar business for Xerox.
Color print film is used to produce color photographic prints, which date to the early 20th century. Initially a two-color process, it became three-color, more accurate, and more durable with the 1935 introduction of Eastman Kodak’s Company’s Kodachrome film, followed a year later Agfa Company’s Agfacolor .

Printed in color from various plates, using etching, engraving, and aquatint. One of the leading achievements of the French 18th-century color-print. Most early methods of color printing involved several prints, one for each color, although there were various ways of printing two colors together if they were separate.
Xerography was invented by American physicist Chester Carlson, based significantly on contributions by Hungarian physicist Pál Selényi. Carlson applied for and was awarded U.S. patent 2,297,691 on October 6, 1942. Carlson's innovation combined electrostatic printing with photography, unlike the dry electrostatic printing process invented by ...
A Xerox digital photocopier in 2010. A photocopier (also called copier or copy machine, and formerly Xerox machine, the generic trademark) is a machine that makes copies of documents and other visual images onto paper or plastic film quickly and cheaply. Most modern photocopiers use a technology called xerography, a dry process that uses ...
