A low-cost printing apparatus for recording data according to a predetermined color bar code on a record medium. The printer apparatus includes a print head composed of a plurality of print elements assembled together, the print elements having opposite or adjacent edge portions each of which contains type elements which print bars in different sequences and in different colors. To complete the printing of a code on a record medium, the print head prints one color with one edge and is then rotated to print a second time, using the other edge, with another color, the recording of the data being completed by the printing with both edges.
