How does a bubble jet printer work?
A bubble jet printer is a type of an inkjet printer which basically jets a particular amount of ink in the paper which is appropriated by the computing chip on the printer. However, the difference is that bubble jet printer heats the ink first before jetting onto the paper. Confused?
Ever seen a mud spring where mud bubbles come out of the ground because of the high temperature? If you look closely to the bubbles coming out of the ground, they usually pop with a small amount of liquid in them. These small amounts of liquid are usually just drops. This is the concept of a bubble jet printer.
The need for inkjet printers which can jet unrecognizable small dots of ink to the paper the fastest way possible but the farther away from the paper possible inspires the invention of a bubble jet printer which propels tiny dots of ink to paper without even reaching the surface of the paper. Usually, a bubble jet printer head has 300-600 small nozzles containing small amounts of ink inside each nozzle.
When the print head starts to continuously move, quickly changing from stop to motion depending on the page position, the resistor in the nozzle of the bubble jet printer head is already being heated by electric shocks.
The heat becomes strong enough to cause the boiling of the ink, causing it to vaporize into a bubble, and propelling it from the print head to a dot printed on the paper. The concept easily draws from the framework of a mud spring.
When one asks, how small are the bubbles that changes into dots in the surface of the paper? The answer is it is too tiny to be seen and will actually take hundreds of them, accurately positioned, before it can make up a simple letter.
