Abstract
Thermal printheads need a power and/or a data cable to deliver energy to the thermal printhead to print. With a wireless thermal printhead, however, a printer can run without using a power or a data cable. By removing the cable, benefits include shrinking the printer size, increasing durability of the printer and making it easier to change a thermal printhead.
