Dynamic strobe compensation control for a barcode printer
United States Patent 5,745,146
Durst , et al. April 28, 1998
Abstract
A dynamic strobe compensation control for a battery powered barcode printer varies the strobe time for the thermal printhead of the printer during the printing of a line of data to compensate for internal resistance losses in the thermal printhead. The control varies the strobe time based upon the measured voltage of the battery powering the printhead when the battery is not loaded by the thermal printhead and when the battery is load by the thermal printhead. The print quality is thus maintained across the width of a line of print data as well as over multiple lines of print data.
