Born in Hungary in 1854, the life of David Gestetner is the history of office copiers. He quit school at the age of 13 and went through the United States to a company in Vienna, Austria, where he built a primitive copy machine, Hectography. He moved back to London in 1979, and two years later, at the age of 27, he invented the Cyclostyle, which used a cogwheel stylus to scrape the original paper. His invention, which thought that the wax-coated paper used to make kites for children flying could be an excellent backbone, sparked a tremendous office revolution. The duplicator not only helped the clerk have to copy each other to make multiple copies of the same document, but it also gave the senior management a tremendous amount of time. For example, 30 people had to read and contrast each of the 30 pages to make sure they were properly transcribed until 20 copies of the agreement on matters involving 30 people. However, starting with the filming machine, all 30 people only had to check one at a time.

After developing a series of three types of flat printers, Gestener's stencil copying machine launched a rotary type copying machine from'Model 3'.

In 1890, Gestenna advertised that he could copy 1,200 copies in an hour with his new Rotary-style imprinter. It was a surprise that I could not even imagine at the time. Jestener died in 1939, but the company he founded continued to develop with his wife and children. Henry Gestener, the daughter-in-law who ran the company after his son, was respected by society for her generous investment in cultural and philanthropy.

The series of dungeons by Jestener, which began in 1881, ended forever with the'Model 4130' released in 1986. 'Model 66' was loved as the most attractive design among the series of lanterns introduced by Jestener for 105 years. 'Model 120' is the successor to the world-renowned designer Raymond Lowe's work,'Model 66', with a light and economical model.

The production of the imprinter came to an end, but Gestener continued to improve by developing office products and printing machines. By 1990, it had operated in 153 countries, more than the number of UN member states at that time. In 1996, it merged with Japanese company Ricoh to produce major products under the name of'NRG Group PLC'.

As a result, it was also referred to as the technique of scratching the original paper with a geared stylus. It is also called Cyclostyle in English.

The company of the same name, founded by Gestetner in 1881, is now operating as a group called NRG Group PLC, which sells printers and fax equipment, after changing its name to its owner.
