There are two main working principles of thermal transfer printers currently on the market: piezoelectric printing and thermal foaming. Epson printers use piezo printing. Piezo printers do not change the chemical properties of the thermal transfer ink because they only change the mechanical pressure. It changes the current of the tiny piezoelectric ceramic sheet of the print head through computer control to make it different. The pressure of the ink ejected from the nozzle to form different shades of image; suitable for thermal transfer. The R210 / 230/270/290 / Me series of the EPSON series are the most suitable printers for personal thermal transfer.
