The printer was invented by John Water and Dave Donald. A device that prints the calculation results or intermediate results of a computer on paper in a prescribed format with numbers, letters, symbols, and graphics that can be recognized by humans. Printers are developing towards being light, thin, short, small, low power consumption, high speed and intelligent.
With the rapid development of the Internet, some people predict that the paperless era is coming and the end of printers has come. However, global paper consumption is increasing at an exponential rate every year, and printer sales are increasing at an average rate of close to 8%. All this indicates that the printer will not only not disappear, but will develop faster and faster, and the application field will become wider and wider.
1. Technology
The basic working principle of inkjet printers is to first produce small ink droplets, and then use the inkjet head to guide the small ink droplets to a set position. The smaller the ink droplet, the clearer the printed picture. The basic principle seems very simple, but the operation is not that simple. Just as the principle of calculus is not complicated, what is complicated is how to use it.
The following introduces several historical technological breakthroughs in inkjet printers.
Time Event Minutes
1976 The world's first inkjet printer was born.
In 1976, piezoelectric ink dot control technology came out.
1979 Bubble Jet bubble jet technology came out.
In August 1980, Canon applied its bubble inkjet technology to its inkjet printer Y-80 for the first time, and the history of inkjet printers began.
In 1991, the first color inkjet printer and large format printer appeared.
1994 Micro piezoelectric printing technology came out.
In 1996 Lexmark used EXCIMER ARGON/FLUMRINE laser cutting technology to launch the world's first 1200*1200dpi ultra-high resolution color inkjet printer Lexmark CJ7000
In 1998, the world's first EPSON Stylus Photo 700 with the highest resolution of 1440dpi and six-color printing was launched.
1998 The world's first 7-color photo printer Canon BJC-7100 was born
1999 EpsonIP-100, the first color inkjet printer that can print A4 photos without using a computer, was born
2000 The first color inkjet printer HP DJ970Cxi supporting automatic duplex printing was born.
2003 HP Photosmart 7960, the world's first digital photo printer with eight-color ink technology, was launched
In the spring of 2005, the world's first 9-color photo printer HP Photosmart 8758 was born
Inkjet printing technology was proposed as early as 1960, but it took 16 years for the first commercial inkjet printer to be born in IBM. The original BM4640 was developed by Professor Hertz and his colleagues at the Lutheran Institute of Technology in Sweden. , Called continuous inkjet technology. The so-called continuous inkjet is to produce ink droplets in a continuous manner regardless of printing or non-printing, and then recycling or dispersing the non-printing ink droplets. However, this technology almost prints ink dots onto paper in a dropwise manner. The difference in effect is imaginable, so it has no practical value in reality.
In 1976, piezoelectric ink dot control technology came out
In the same year as IBM4640, the three pioneer researchers Zoltan, Kyser and Sear of Siemens Technology successfully developed and developed piezoelectric ink dot control technology (the predecessor of EPSON technology) and successfully applied it to Seimens Pt-80. The printer was mass-produced and sold in 1978, becoming the world's first inkjet printer with commercial value. In 1979, Bubble Jet bubble inkjet technology came out
Researchers from Canon in Japan have successfully developed the Bubble Jet technology. This technology uses a heating element to instantly heat the ink in the nozzle to generate bubbles to form pressure, so that the ink is ejected from the nozzle, and then the physical properties of the ink itself are used to cool the hot spots. The bubbles disappear, thereby achieving the dual purpose of controlling the in and out of ink dots and the size. Here is a short story of the company. On one day in July 1977, Ichiro Endo of the 22nd Laboratory of the Canon Product Technology Research Institute in Meguro-ku, Tokyo, accidentally put a heated soldering iron in the injection laboratory while conducting an experiment in the laboratory. On the attachment of the needle, ink quickly flew out of the injection needle. Inspired by this, bubble inkjet technology was invented 2 years later.
At the same time, HP has invented essentially the same technology. HP and Canon both claimed that their researchers were the first to invent inkjet printing technology to establish their position in the field of inkjet printing. However, the concept of "bubble" has been snatched by Canon, and HP had to name it Thermal Ink-Jet.
In 1991, the first color inkjet printer and large format printer appeared
The HP HP deskjet 500C is the world's first color inkjet printer. In June 1994, the HP DeskJet 525Q, a product modified locally, only appeared in China. HP DesignJet is the first time that Hewlett-Packard Company applied its thermal inkjet printing technology to a large format printer, and launched the world's first monochrome large format inkjet printer. The emergence of color inkjet printers and large format printing are the most important milestones in the history of inkjet printers.
In 1994, micro-piezo printing technology came out
As early as the 1970s in the last century, Epson began the research of piezoelectric technology. After nearly 20 years, it finally successfully applied micro-piezo printing technology to the printer field and realized commercialization. The basic principle of micro-voltage technology is to place many tiny piezoelectric ceramics near the nozzle of the print head of an inkjet printer, and use the principle that the ink deforms under the action of voltage, so that the ink in the nozzle is ejected and formed on the surface of the output medium. pattern.
Since then, Epson's intelligent ink drop transformation technology, natural color reproduction technology, ultra-precision micro ink drop technology, etc.; Canon's professional photo optimization technology, quadruple color control technology, etc.; HP's Wealthy image layering technology, intelligent color enhancement technology, etc. Both have further improved the technical content of inkjet printers
