ABSTRACT:
A method of printing a pre-defined symbology character set as a series of bars separated by spaces in which the bars are formed of horizontal rows of close adjacent dots while preventing ambiguous decoding of similar character pairs in which one character employs wide bars and one character employs narrow bars. The method comprises the steps of, subtracting at least a portion of one dot or more per horizontal row from bars of similar characters employing narrow bars; and, adding at least a portion of one dot or more per horizontal row to bars of similar characters employing wide bars. It is particularly useful in printing U.P.C./EAN symbology with a low-cost demand printer employing thermal printing techniques.
