Code printing method and code format

摘要

The present invention relates to a code printing method and a code format, capable of accurate recognition of codes. Printing by nozzles excluding nozzles at one end out of nozzles of a printer head prevents codes printed by the scanning of the printer head from overlapping at each scanning as shown by a portion surrounded by an oval part in the drawing to permit accurate printing of codes. In addition, by printing a synchronizing code column, positions of printed dots can be accurately detected to thereby permit accurate recognition of printed codes.
