Why Is Print Head So Important?
The print head is the core component of the printer and the only channel for ink output. Its performance directly determines the printing quality.
The important role of the print head is mainly reflected in the following aspects:

Ink Droplet Formation and Injection: The print head uses a precise mechanical system and electronic control. It injects ink onto the medium in exact amounts and speeds to form tiny droplets. The size, shape and injection speed of the ink droplets directly affect the clarity, fineness and color reproduction of the printed image.
Resolution: The nozzle density on the print head determines the resolution of the printer. The higher the nozzle density, the more ink droplets can be injected per inch, and the finer the printed image.
Printing Speed: The injection frequency and number of nozzles of the print head determine the printing speed. The higher the injection frequency and the more nozzles, the faster the printing speed.
Printing Accuracy: The nozzle arrangement and control accuracy of the print head determine the printing accuracy. The more precise the nozzle arrangement and the higher the control accuracy, the clearer the printed image and the smoother the lines.
Ink Compatibility: Different print heads have different requirements for ink viscosity, surface tension and other characteristics.
