Overview
Dataproducts was an early American computer-peripherals company whose history spans the transition from mainframe computing equipment to office and industrial printing supplies. Founded in 1962 as Data Products by Erwin Tomash and other associates, the company was created to assume control of Telex’s Data Systems Division. That division was behind schedule on a disk-drive contract for General Electric, and the newly established company completed the equipment and delivered it to General Electric and subsequently to customers including Ferranti, ICL, and RCA. The company soon broadened its activities. Its first major printer was the 3300, introduced in 1963 as a 300-line-per-minute drum printer. The machine used a moving-coil actuator to operate its print hammers and helped establish Dataproducts in high-speed computer printing. Core memory became another important product area in 1966. Dataproducts also created Informatics as a subsidiary for contract software work; Informatics later developed MARK IV, an influential fourth-generation programming language, before being spun off as a public company in 1968. Growing sales and earnings led Dataproducts to move to a larger facility in Woodland Hills, Los Angeles, in 1968. The company expanded through acquisitions, including Staff Dynamics, a personnel agency, and Uptime, a maker of card readers. Graham Tyson succeeded Tomash as chief executive in 1971. The original disk-drive business eventually deteriorated under competitive pressure and was discontinued, leaving printing and related equipment as the company’s principal focus. During the 1970s and 1980s, Dataproducts developed a broad printer portfolio. It moved from drum printers toward band technology, added dot-matrix products, and marketed thermal printers sourced from Olivetti. Daisy-wheel printers were added after the company acquired that business from Plessey in 1978. Dataproducts also pursued solid-ink printing in cooperation with Exxon and participated in the development of plastic-card embossing equipment through Data Card. Its telecommunications expansion included the purchase of Stelma. The solid-ink program generated significant intellectual-property disputes. Dataproducts sued Howtek over the use of hot-melt ink, delaying Howtek’s Pixelmaster color printer and raising its manufacturing costs before the case was dropped. Dataproducts also became involved in patent litigation with Tektronix and Apple. The disputes consumed resources; Apple discontinued its related product, while Tektronix ultimately paid royalties. In 1986, Jack C. Davis replaced Graham Tyson as chairman and chief executive. By the end of the 1980s, Dataproducts was under financial and strategic pressure. Net income had fallen from a reported peak of $27.7 million to $3.8 million by 1989, and the company resisted takeover attempts by a consortium. Hitachi acquired Dataproducts in 1990. Under Hitachi ownership, the business continued to develop laser printers using Fuji Xerox engines, including the Typhoon family. The LZR1560 and LZR1580 were also sold to Apple as the LaserWriter Pro 810 in 1993, and Dataproducts announced the LZR 5200 continuous-feed laser printer in 1998. The original Dataproducts brand was incorporated into Hitachi Koki Imaging Systems in 1999. A later continuation of the name emerged in compatible consumables: Clover Technologies Group acquired the North American and European compatible printing-supplies divisions of Ricoh Printing Systems America in 2005, including the Dataproducts brand. Dataproducts supplies subsequently operated within Clover, with distribution in Simi Valley, manufacturing facilities in Mexicali and Porto, and a product focus on printer, fax, and copier consumables. Thus, Dataproducts evolved from a mainframe equipment manufacturer into a printing technology and supplies brand, with its present identity tied principally to compatible imaging consumables rather than to the original computer-hardware corporation.
History
Dataproducts originated in 1962 when Erwin Tomash and associates established Data Products to take control of Telex’s Data Systems Division. The inherited operation was late delivering disk drives to General Electric, but Dataproducts completed the work and later supplied comparable equipment to Ferranti, ICL, and RCA. The company used this early disk-drive business as a base for diversification. Its most important early expansion was into computer printing. The 3300, introduced in 1963, was a 300-line-per-minute drum printer with moving-coil print-hammer actuation. Core memory was added in 1966, and the company moved to a larger Woodland Hills, Los Angeles facility in 1968 as sales increased. Dataproducts also formed Informatics, a software subsidiary led by Walter F. Bauer. Informatics acquired Advanced Information Systems from Hughes Dynamics, developed the MARK IV file-management and programming system, and was spun off in 1968. After Graham Tyson became chief executive in 1971, Dataproducts reduced its reliance on disk drives as competition weakened that business. The company acquired Staff Dynamics and Uptime, bought Stelma, and created Data Card for plastic-card embossing equipment. In printing, it moved from drum technology toward band printers, dot-matrix machines, thermal printers sourced from Olivetti, and, after a 1978 transaction with Plessey, daisy-wheel printers. A joint project with Exxon also produced solid-ink printing technology. Solid-ink patents became a major source of litigation. Dataproducts sued Howtek over hot-melt ink technology, delaying shipment of the Pixelmaster color printer before Dataproducts abandoned the action. Separate legal conflicts with Tektronix and Apple over solid-ink patents consumed resources; Apple discontinued its product, while Tektronix paid royalties. Jack C. Davis succeeded Tyson as chairman and chief executive in 1986. The company’s financial position deteriorated late in the decade. Reported net income fell from $27.7 million at its high point to $3.8 million in 1989, while Dataproducts faced takeover attempts. Hitachi acquired the company in 1990. Dataproducts subsequently used Fuji Xerox printer engines in the Typhoon series and supplied the technology behind Apple’s LaserWriter Pro 810 through the LZR1560 and LZR1580. It announced the LZR 5200 continuous-feed laser printer in 1998. In 1999, the Dataproducts name was absorbed into Hitachi Koki Imaging Systems. The name later continued in compatible imaging supplies after Clover Technologies Group acquired the relevant Ricoh Printing Systems America divisions in 2005. The present brand is therefore principally associated with compatible consumables for printers, fax machines, and copiers, rather than with the original Dataproducts corporation’s mainframe peripherals.
