In 1970, Centronics (then of Hudson, New Hampshire) introduced a dot matrix printer, the Centronics 101. The search for a reliable printer mechanism led it to develop a relationship with Brother Industries, Ltd. of Japan, and the sale of Centronics-badged Brother printer mechanisms equipped with a Centronics print head and Centronics electronics. Unlike Digital, Centronics concentrated on the low-end line printer marketplace with their distinctive units. In the process, they designed the parallel electrical interface that was to become standard on most dot matrix printers (indeed, most printers in general) until it started to be replaced by the Universal Serial Bus (USB) in the late 1990s.
DeskJet is a brand name for inkjet printers manufactured by Hewlett Packard. These printers range from small domestic to large industrial models, although the largest models in the range have generally been dubbed DesignJet.
HP developed thermal inkjet technology in 1979 and launched their ThinkJet in 1984, with colour following in 1987 thanks to the PaintJet. The first DeskJet printer, with a black ink cartridge followed in 1988. Priced at $1000, it was claimed to be able to rival laser printer quality. It was the least expensive non-impact printer on the market at the time it was introduced, when most small non-laser printers were still impact-based and laser printers remained relatively expensive. The first colour DeskJet, the 500C, launched in 1991.
The first laser printer was produced by Xerox when Xerox researcher Gary Starkweather modified a Xerox copier in 1971. Laser printing eventually became a multibillion-dollar business for Xerox.
