INKJET PRINTER(1977)

Endo invents a new printing method.

Inkjet printer is a type of printer in which the letters are made with the help of ink. inkjet printing is type of computer printing that recreate the digital image. Most useful technological take time to mature; usually there are at least a couple of years between an idea’s conception and a final working model. When it comes to inkjet printing, however, it took much longer the patent for directing ink onto paper using electrostatic force was granted to Lord Kelvin in 1867.

Before the 1980s, printing from a computer was a slow, unrewarding task. The mechanisms behind those early printers used moving parts, bladders and pump that made them expensive, inefficient and clumsy. The modern inkjet was to change all this by using heat or electrostatic force to produce uniform droplets and precision results. In Japan in the 1970, canon and Hewlett Packard were competing with each other to produce the first reliable inkjet printer.

Hewlett Packard was beaten by a canon researcher named Ichiro Endo who invented the first thermal inkjet printer in 1977. He was inspired when he saw a syringe full of ink accidantly being touched with a hot soldering iron. The heat caused the ink to increase in volume and spurt out. Endo realized this was the solution to delivering controlled spurts of ink, and within the days he produced the working model that later became the canon bubble jet printer.

Both Hewlett Packard and canon put in patents within months of each other, and although there is much discussion about who invented what first. The two companies ended up sharing a lot of printing technologies with each other. The winner, with high quality cheaply produced printers available to all, was the home consumers. Now a day inkjet printers are used in any fields like in office, business, hospitals etc.
