Abstract
Method and apparatus for printing a scannable bar code pattern is described. A high speed bar code printer produces a line spacing distance to a preselected value so that a plurality of identical horizontal lines of vertically oriented code bars may be printed in vertical overlapped relation so as to form a single vertically heightened bar code. This taller bar code pattern is more easily and efficiently scanned with the optical read head.
