There are two main working principles of heat transfer printers on the market: piezoelectric printing and thermal foaming. Epson printer uses piezoelectric printing. The piezoelectric printer will not change the chemical properties of the thermal transfer ink because only the mechanical pressure is changed. It uses computer control to change the current of the tiny piezoelectric ceramic chip of the print head to generate different pressures to spray ink from the nozzle to form images of different depths; Suitable for heat transfer printing.Thermal transfer printer. It is also called thermal printer. During printing, many small heating elements on the printing head heat the ribbon. After contacting with the printing paper, thousands of control units on the thermal printing head heat and melt the color wax, and spray it on the special paper or transparent film.

Heat transfer printing generally requires three or four color bands, and a color page needs to be printed three to four times. The heat transfer printer can use ordinary paper with high printing accuracy and bright colors, but it is slow in printing speed and expensive in cost and operation.
