Chester Carlson invented a dry printing process called electrophotography, commonly known as a Xerox, in 1938. In 1953, the first high-speed printer was developed by Remington-Rand.
Using electrophotography as the basis for laser printers, the Xerox Palo Alto Research Center began development on the first laser printer, called EARS, in 1969 and completed it in 1971. While the inkjet printer was invented in 1976, it took until 1988, the release date of Hewlett-Packard's DeskJet, for it to become available for use in the home. In 1992, Hewlett-Packard released the popular LaserJet 4, which was the first 600-by-600 dots per inch resolution printer.
