In 1938, Chester Carlson, an American physicist and inventor, invented a dry printing process called ‘electro photography’. It is commonly called a ‘Xerox’. In 1953, the first high-speed printer was developed by Remington-Rand for use on the Univac computer. In 1969, the original laser printer, called EARS, was developed at the Xerox Palo Alto Research Centre in California. Gary Starkweather added a laser beam to the Xerox technology to come up with the laser printer.
