摘要： 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.

摘要： A thermal head of a thermal printer is provided with an array of parallel connected heating elements and transistors connected in series to the heating elements in one to one relation. In a resistance measuring mode, one of the transistors connected to one heating element whose resistance is to measure is turned on, and other transistors are turned off. In this condition, a capacitor connected in parallel to the heating element is charged up to a predetermined voltage, and then discharged. A counter circuit starts time-counting by a short unit time t0 when a predetermined delay time T min has passed since the start of discharging, and outputs a count Q when the charged voltage goes down to a predetermined level. Based on a discharge time T=T min+t0·Q, the resistance of the heating element is calculated.

摘要： The present invention provides a method of performing a burn cycle in a thermal printer that reduces printhead switching while increasing printing speed and extending printhead life. In the method, data is loaded into a shift register of a thermal printhead to designate resistive elements that are to be enabled and disabled during the burn cycle. Next, the data is latched into a burn register of the printhead and a power supply of the printhead is activated thereby energizing the enabled resistive elements. New data is then loaded into the shift register. After a short burn period has expired, the new data is latched into the burn register. The steps of loading and latching new data are repeated a predetermined number of times, after which the power supply is deactivated to complete the burn cycle.
