HP in the inkjet printer industry usually refers to the HP HP brand inkjet printhead, which is usually installed on thermal foaming high-resolution inkjet printers.

HP thermal bubble inkjet technology; the nozzle adopts semiconductor thin film technology, adopts laser process and high-precision coating technology to form multiple nozzles with a diameter of about 50 microns

hole. These nozzles are arranged in high density. After receiving the heating signal, the ink is heated to about 260°C by electric current in a very short moment, and the local ink is heated to form bubbles that expand and eject the ink.

Features of HP high-resolution inkjet printers: Because high temperature is easy to make the nozzle material rust, the life of this type of nozzle is relatively short.
