In this laser printer made by Gary Starkweather who was an engineer in Xerox, the technology of Xerox copier is used with laser beam and in the year 1977, he launched a xerographic laser printer manufactured good, Xerox 9700 electronic printing system which brought revolution in the development of laser scanning products.
