Abstract

A bar code printing method for generating extended height bar code image target patterns and human readable matter in combination therewith on bar coded items, such as labels, forms, papers and the like which enables the unmodified utilization of currently available computer driven pulsing hammer raise-engraved fixed font printers of that type wherein the long axis of the bar code font characters are disposed parallel to the lateral edge direction of pitch advance feed of the print stock material wherein the printing method is accomplished by the technique of utilizing raise-engraved bar code characters in the printing font which are of a slightly greater elevation than the pitch advance of the printing stock whereby each successive impact printed bar code character image on printing stock pitch advance vertically registers on and slightly overlaps the previously printed image thereof and thus produces a continually printed bar code image target pattern to a line length of any multiple of pitch advances desired in turn thus to produce an extended height bar code image target pattern of a sufficient size so as to enhance either the manual or mechanical presentation thereof to the optical sensing head of an electronic scanner-reader and thereby in turn enhance facilitated scanner-reader bar code image target pattern acquisition and sensing with greater accuracy.
