How were computer printers created?


How were computer printers created?

In 1953, Remington-Rand developed the first high-speed printer for use on the Univac computer. In 1938, Chester Carlson invented a dry printing process called a Xerox, the foundation technology for laser printers to come.


The original laser printer called EARS was developed at the Xerox Palo Alto Research Center in California, USA, and completed by November 1971. Xerox Engineer, Gary Starkweather adapted Xerox copier technology, adding a laser beam to it to come up with the laser printer. In 1992, Hewlett-Packard released the popular Laser Jet4, the first 600 by 600 dots per inch resolution laser printer.
