Abstract
A thermal print pulse controller and data shifter accomplishes control of a thermal print pulse by altering the pulse width of the print pulse according to the printing history. Data is obtained from the printhead and recirculated for logical operation with previous records back to the printhead during predetermined phases of the print pulse. As a result of the logical comparison a decision is made to continue or discontinue printing of a dot and thus prevent overheating the printing element.
