<P> Most consumer inkjet printers , such as those made by Canon , HP , and Lexmark ( but not Epson ) use a thermal inkjet ; inside each partition of the ink reservoir is a heating element with a tiny metal plate or resistor . In response to a signal given by the printer , a tiny current flows through the metal or resistor making it warm , and the ink in contact with the heated resistor is vaporized into a tiny steam bubble inside the nozzle . As a consequence , an ink droplet is forced out of the cartridge nozzle onto the paper . This process takes a fraction of a millisecond . </P>
