What is the difference between piezoelectric inkjet technology and thermal inkjet (TIJ) technology?
A. A piezo inkjet printer head uses a piezoelectric crystal to force ink through small nozzles and onto the print media. A piezoelectric crystal changes shape when an electric current passes through it. It acts like a tiny piston to move the ink. Thermal inkjets use electricity to provide heat. It brings the ink droplet to a boil at the point the heat is applied. Some of the liquid turns to vapor, and the rapid expansion of the gas jettisons the ink through the nozzle.
