Abstract
A thermal printer is operated to adjust the level of energy applied to print elements of a print head of the printer in response to selected changes in signals corresponding to the voltage from a power source used to provide energy to the printing elements. Voltage changes that occur during printing of a print can be ignored. In addition, voltage changes occurring when a printer is not being powered by a battery can also be ignored. Rapid decreases in voltage of the power source can be detected and accounted for. In addition, increasing voltages of the power source can also be determined and accounted for.
