摘要:
The present disclosure relates to a replaceable ink cartridge for providing ink to an ink-jet printer. The replaceable ink cartridge includes a memory associated with the replaceable ink container. The memory has a single data terminal and a reference terminal. The memory is responsive to control signals provided to a single data terminal relative to the reference terminal by the ink-jet printer for providing a data signal representative of stored information to the single data terminal relative to the reference terminal. The data signal is sensed by the ink-jet printer for adjusting printer operation.
摘要:
A technique of forming a bar of a bar code on print media by a printing device having a plurality of colorants. Each one of the individual bars has a leading edge and a trailing edge that help to define a central region of the bar. The relative locations of the leading edge and trailing edge are determined and a first colorant, usually black, is deposited at the leading edge. A composite of the first colorant, and the other printhead colorants, are deposited in the central region while the first colorant is deposited at the trailing edge. A bar of a bar code produced by this technique has a clearly defined leading and trailing edge for bar code readers to measure while the central region of the bar includes a composite of colorants.
