Xerox Engineer Gary Starkweather born adapted Carlson's Xerox copier technology, adding a laser beam to it to come up with the laser printer. According to the Xerox Corporation, "The Xerox Electronic Printing System, the first xerographic laser printer product, was released in The , a direct descendant from the original PARC "EARS" printer which pioneered in laser scanning optics, character generation electronics, and page formatting software, was the first product on the market to be enabled by PARC research.
It was a laser printer that operated at speeds of more than impressions-per-minute. It was the first printer to combine laser technology and electrophotography. In , Hewlett-Packard released the popular LaserJet 4, the first by dots per inch resolution laser printer. Printing is, of course, far older than the computer. However, it is suspected that book printing may have occurred long before this date. Before Johannes Gutenberg ca — , printing was limited in the number of editions made and nearly exclusively decorative, used for pictures and designs.
The material to be printed was carved into wood, stone, and metal, rolled with ink or paint and transferred by pressure to parchment or vellum.
Books were hand copied mostly by members of religious orders. Gutenberg was a German craftsman and inventor, and he is best known for the Gutenberg press, an innovative printing press machine that used movable type.
It remained the standard until the 20th century. Gutenberg made printing cheap. German born Ottmar Mergenthaler's — invention of the linotype composing the machine in is regarded as the greatest advance in printing since Gutenberg's development of movable type years earlier, allowing people to quickly set and breakdown an entire line of text at once. In , Samuel Simon of Manchester England was awarded a patent for the process of using silk fabric as a printing screen.
Using materials other than silk for screen printing has a long history that begins with the ancient art of stenciling used by the Egyptians and Greeks as early as B. Walter W. Morey of East Orange, New Jersey, conceived the idea of a teletypesetter, a device for setting type by telegraph using coded paper tape.
He demonstrated his invention in , and Frank E. Siemens developed the first DOD drop-on-demand inkjet printer in The DOD printer sprays ink where it is needed on the piece of paper.
Canon introduced the LBP, the first semiconductor laser beam printer and their first printer unit. It was considered the first mass-marketed inkjet printer and became a very popular and widely used series of printers.
Many modern 3D printers use a technology called FDM fused deposition modeling , which was developed and patented by Scott Crump in Stratasys, Inc. Scott Crump. Unlike typewriters, these printers produce any character or graphic. When Remington-Rand introduced the high-speed printer for the Universal Automatic Computer Univac , it was a big and bulky machine that only modernized offices used. Typewriters were still the popular way of printing characters during that time.
Though high-speed, users had to go through a lot of processes in order to print one piece of paper. Companies debated between impact and non-impact printers, as they varied in cost and effectiveness. Impact printers produce a high amount of paperwork, but with low-resolution graphics.
Non-impact printers yield high-quality prints, but at a much slower pace. Daisy wheel, line printers, and dot matrix printers are impact printers as they operate by striking an ink ribbon. Laser, inkjet, and other modern printers are non-impact printers. Gary Starkweather used the copier technology in Xerox machines to develop the first laser printer in
