Patent attributes
A method of controlling thermal printing based upon print density. The method includes receiving pre-formatted data representing information to be printed on two sides of a thermal print media from a computer by a processor of a thermal printer, analyzing the pre-formatted data by the thermal printer to determine different types of data to be printed with different print densities by the processor, determining an average print density of the different print densities by the processor, determining that the average print density is greater than a predetermined average print density by the processor, determining a power level required to print the data, and directing first and second thermal print heads to print the data based upon the required power level by the processor.
