2003 HP Photosmart 7960, the world's first digital photo printer using eight-color ink technology, is released
Spring 2005 The world's first 9-color photo printer, the HP Photosmart 8758, is born
Inkjet printing technology was proposed as early as 1960, but it took 16 years for the first commercial inkjet printer to be born at IBM, and the original BM4640 was developed by Hertz, a professor at the Luther Institute of Industrial Technology in Sweden, and his colleagues in Europe, called continuous inkjet technology. The so-called continuous inkjet is to produce ink droplets in a continuous way, regardless of whether it is printed or non-printed, and then the non-printed ink droplets are recycled or dispersed. However, this technology almost uses drops to print ink dots on paper, and the effect is imaginable, so it has no practical value in reality.
In 1976, piezoelectric ink dot control technology was introduced
In the same year as the IBM 4640, Zoltan, Kyser and Sear, three pioneer researchers of Siemens Technologies, successfully developed piezoelectric dot control technology (the predecessor of EPSON technology) in the same year and successfully applied it to the Seimens Pt-80, which was mass-produced and sold in 1978, becoming the world's first commercially valuable inkjet printer. In 1979, the Bubble Jet bubble inkjet technology was introduced
Researchers at Canon in Japan have successfully developed Bubble Jet bubble inkjet technology, which uses a heating component 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 to fade the bubbles, so as to achieve the dual purpose of controlling the ink spot in and out and size. To quote a short story from the company, one day in July 1977, Ichiro Endo, a member of Laboratory 22 of the Canon Product Technology Research Institute in Meguro-ku, Tokyo, accidentally placed a heated soldering iron on the attachment of the injection needle while conducting experiments in the laboratory, and ink quickly flew out of the injection needle. Inspired by this, bubble inkjet technology was invented two years later.
At the same time, HP also invented the same technology, HP and Canon both claimed that their researchers were the first to invent inkjet printing technology, in order to establish their position in the field of inkjet printing. However, the concept of "bubbles" has been snatched up by Canon, and HP has to name it Thermal Ink-Jet.
In 1991, the first color inkjet printer, large-format printer, appeared
HP deskjet 500C is the world's first color inkjet printer, in June 1994, the domestic product HP DeskJet 525Q after local transformation. HP DesignJet is the world's first monochrome large-format inkjet printer introduced by Hewlett-Packard to apply its thermal inkjet printing technology to a large-format printer. The emergence of color inkjet printers and large-format printing is the most important milestone in the history of inkjet printers.
In 1994, micro-piezoelectric printing technology came out
As early as the 70s of the last century, Epson began the research of piezoelectric technology, and after nearly 20 years, it finally successfully applied micro-piezoelectric printing technology to the field of printers and realized productization. The basic principle of microvoltage technology is to place many tiny piezoelectric ceramics near the printhead nozzle of the inkjet printer, and use the principle that the ink will deform under the action of voltage, so that the ink in the nozzle is ejected, forming a pattern on the surface of the output medium.
Since then, Epson's intelligent ink drop transformation technology, natural color reduction technology, ultra-fine micro ink drop technology, etc.; Canon's professional photo optimization technology, quadruple color control technology, etc.; HP's Fullitu layering technology, intelligent color enhancement technology, and more. All further enhance the technical content of inkjet printers.
