Control Data Corporation
Centronics Data Computer Corporation was an American manufacturer of computer printers, now remembered primarily for the parallel interface that bears its name.
Centronics began as a division of Wang Laboratories. Founded and initially operated by Robert Howard (president) and Samuel Lang (vice president and owner of the well known K & L Color Photo Service Lab in New York City), the group produced remote terminals and systems for the casino industry. Printers were developed to print receipts and transaction reports. Wang spun off the business in 1971 and Centronics was formed as a corporation in Hudson, New Hampshire with Howard as president and chairman.
The Centronics Model 101 was introduced at the 1970 National Computer Conference. The print head used an innovative seven-wire solenoid impact system. Based on this design, Centronics later made the (incorrect) claim to have developed the first dot matrix impact printer (while the first such printer was the OKI Wiredot in 1968).
Howard developed a personal relationship with his neighbor, Max Hugel, the founder and president of Brother International, the United States arm of Brother Industries, Ltd., a manufacturer of sewing machines and typewriters. A business relationship developed when Centronics needed reliable manufacturing of the printer mechanisms—a relationship that would help propel Brother into the printer industry. Hugel would later become executive vice president of Centronics. Print heads and electronics were built in Centronics plants in New Hampshire and Ireland, mechanisms were built in Japan by Brother and the printers were assembled in New Hampshire.
In the 1970s, Centronics formed a relationship with Canon to develop non-impact printers. No products were ever produced, but Canon continued to work on laser printers, eventually developing a highly successful series of engines.
In 1977, Centronics sued competitor Mannesmann AG in a patent dispute regarding the return spring used in the print actuator.
In 1975, Centronics formed an OEM agreement with Tandy and produced DMP and LP series printers for several years. The 6000 series band printers were introduced in 1978. By 1979 company revenues were over $100 million.
In 1980, the Mini-Printer Model 770 was introduced—a small, low-cost desktop serial matrix printer. This was the first printer built completely in-house, and there were problems. Flaws in the microprocessor led to a recall and a stoppage of manufacturing for a year. During this period, Epson, Brother and others began to gain market share and Centronics never recovered. 1980 also saw the introduction of the E Series 900 and 1200 LPM band printers.
Change of ownership
In 1982, Control Data Corporation merged their current printer business unit, CPI, into Centronics and at the same time invested $25 million in the company, effectively taking control from Howard. Control Data controlled the company until 1986 when CDC's interest was acquired by a group of investors affiliated with Drexel Burnham Lambert. The Drexel interest was acquired by Centronics in 1987.
The LineWriter 400 band printer was introduced in 1983, closely followed by the faster LineWriter 800 band printer in 1984. The LineWriter series would continue through 1995. The GLP (Great Little Printer) was a series of low-end serial matrix printers introduced in 1984.
The relationship with Brother continued with several of the PrintStation models being produced from rebadged Brother products. Exclusive rights to market Trilog color matrix printers was acquired in 1984, and Trilog was purchased outright in 1985. Advanced Terminals (a manufacturer of sheet feeders) and BDS Computer Australia Pty Ltd were purchased in 1986.
The PrintStation 350 series serial matrix printer was highly successful in the OEM market, sold with the logos of Data General, ITT Courier, NCR, CDC, Decision Data and ISI. Most profitable was the agreement to build the IBM 4214 based on a modified PS350. In 1985, company revenues were $126 million with $65 million from IBM 4214 production. In 1986 the IBM 4214 production ended and revenue dropped.
On June 23, 1986, Centronics announced the new corporate logo. The new logo never gained recognition before the sale to GENICOM, and GENICOM used the old logo in continued sales of printers and supplies.
The only Centronics laser product was released in July 1986: the PagePrinter 8. The PP8 used a Sharp engine identical to an existing Sharp copier, using a 6800 based controller jointly developed by Sharp and Centronics. At $2,495, the PP8 was $500 less than the HP LaserJet. A faster version was announced, but never materialized.
Printer division sale
In 1987 the Centronics printer business was sold to GENICOM. Centronics Data Computer Corporation continued as a New York Stock Exchange company and soon changed its name to Centronics Corporation in 1987. After using the proceeds of the sale to purchase Ekco Housewares in 1988, Centronics changed their name to EKCO Group.
The 101 was highly innovative and affordable at its inception. Some selected specifications:
- Print speed: 165 characters per second
- Weight: 155 pounds (70,3kg)
- Size: 27 ½ " W x 11 ¼ " H x 19 ¼ D (~ 70cm x 29cm x 49cm)
- Shipping: 200 pounds (ca 91kg), wooden crate, unpacked by removal of 36 screws
- Characters: 62, 10 numeric, 26 upper case and 26 special characters (no lower case)
- Character size: 10 characters per inch
- Line spacing: 6 lines per inch
- Vertical control: punched tape reader for top of form and vertical tab
- Forms thickness: original plus four copies
- Interfaces: Centronics parallel, optional RS-232 serial
The connectors developed for its parallel interface live on as the "Centronics connector", used in other computer applications.
