Abstract
A barcode printer stores a list of failed printhead elements. From data associated with a record member, i.e. label, tag or the like, to be printed, a microprocessor of the barcode printer determines left and right boundaries of a print zone for that record member. The microprocessor determines which failed printhead elements in the stored list fall within the boundaries of the print zone to generate a sublist of failed printhead elements in the print zone so that the bad dots that affect printing can more quickly and easily be dealt with.
