The basic working principle of an inkjet printer is to generate small ink droplets first, and then guide the small ink droplets to a set position with an inkjet head. The smaller the ink drops, the clearer the printed picture will be. The outstanding advantages are small size, simple and convenient operation, low printing noise, and the use of special paper can also print pictures comparable to photos.
Extended data:
When the ink-jet printer receives the printing signal, the printing data driving circuit applies an electric pulse signal to the print head, and the electric heating element in the print head will rapidly heat up, so that the ink inside the print head will rapidly rise in temperature and vaporize to form small bubbles, which will expand after continuous preheating, and the internal pressure will squeeze the ink out of the nozzle, and the cooling bubbles of the electric heating element will begin to cool down, and the ink will shrink back to the nozzle, and the ink droplets formed at the nozzle will be sprayed onto the surface of the printing medium to form patterns or characters.
Unlike laser printing, inkjet printing does not have the problem of generating a whole page at one time, so it does not need much memory. The change from the first generation of products to today is only the technical progress, which makes the ink droplets smaller (currently the lowest 1pl), with higher accuracy, and can achieve extremely high photo printing quality through the configuration of more ink, which laser printing can never do.
