Abstract: A system and method for developing a bar code representing the encoding of a set of data, in which the bar code includes pixels having one black level, one white level and at least one gray level, generates a multi-level data representation of the set of data, the number of levels corresponding to the sum of the black level, the white level and the number of gray levels. A pixel color is determined for each component of the multi-level data representation, a pixel color for at least one of the components being one of the at least one gray levels. The determined pixel color is then printed for each component to form the bar code.

Abstract: A system and method are provided for printing a code on a print medium. In one embodiment, the system includes a laser printing assembly within a printer for printing on a print medium. The system also includes an ink jet head assembly attached to a printer structure of the printer for printing a code or other information on the print medium. The ink jet head assembly may be immovably or adjustably attached to the printer structure. The ink jet head assembly may be immovably attached to the printer, for example, by affixing the ink jet head assembly directly to the printer structure or by using a bracket to mount the ink jet head assembly to the printer structure. There are also several alternatives that may be employed to adjustably attach the ink jet head assembly to the printer structure including, for example, a slide assembly, a telescopic assembly, or a swivel arm assembly as well as other suitable adjustable attaching approaches.

Abstract: A method for printing barcode, comprising the steps of obtaining a 1D barcode for an area of a medium; obtaining a 2D bar code; combining the 1D and 2D bar codes in the area to overlap at least in part; and printing the combination of the 2D barcode with the 1D barcode in the area of the medium.
