<p>A thermal printing system includes a print head including a number of thermal printing elements (R1-RN) greater than needed for the maximum number of characters to be printed. For each successive line of characters to be printed, the print data is shifted incrementally with respect to the thermal printing elements (R1-RN) by utilizing a position control value to control a number of binary zero bits stepped into a shift register (25) for the character segment data. The position control value is incremented for each line of characters up to a predetermined value and then returned to zero. Thus, overutilization of certain thermal printing elements (R1-RN) caused by successive printing of identical characters is avoided. In the preferred embodiment, the lines of characters are monetary amounts printed on respective individual checks. </p> |
