History


The beginning

Wang Laboratories

Wang Laboratories was a computer company founded in 1951 by Dr. An Wang and Dr. G. Y. Chu. The company was successively headquartered in Cambridge, Massachusetts , Tewksbury, Massachusetts , and Lowell, Massachusetts ....
. 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

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 claim to have developed the first dot matrix impact printer

Howard developed a personal relationship with his neighbor, Max Hugel, the founder and president of Brother International, the US arm of Brother Industries, 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

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.

 compatibility mode. The original Centronics implementation called for the busy lead to toggle with each received line of data (busy by line), whereas IEEE 1284 calls for busy to toggle with each received character (busy by character). Some host systems or print servers may use a strobe signal with a relatively low voltage output or a fast toggle. Any of these issues might cause no or intermittent printing, missing or repeated characters or garbage printing. Some printer models may have a switch or setting to set busy by character; others may require a handshake adapter.
