Description: The Electrostatic Jet printer (ESJET) is a high-resolution digital printing technology. It uses high voltages that, when applied to a fluid (ink) in short pulses, cause droplets of ink to eject from the print head and land on an electrically grounded substrate.

It is used for research purposes, mainly to deposit electrically conductive nanoparticle inks on a small scale, but many other ink types are possible.
