Abstract:
1. A printing apparatus capable of mounting a multi-color integrated printing material container having a storage device that stores identification information of the printing material container and ink consumption information of each color, the printing apparatus comprising: a first nonvolatile memory that stores the identification information of printing material containers mounted one or more times in the printing apparatus, and first usage information that is based on the ink consumption information of each color of the printing material containers; a second nonvolatile memory; and a printing apparatus controller that controls print processing, wherein the printing apparatus controller compares usage information on the printing material container side that is based on the ink consumption information of each color read from the storage device of a printing material container that is mounted in the printing apparatus with the first usage information associated with identification information that is the same as the identification information of the printing material container that is mounted in the printing apparatus, and executes error processing of the storage device of the printing material container, in a case where a relation between the usage information on the printing material container side and the first usage information does not satisfy a preset relation, wherein the second nonvolatile memory stores the identification information and the ink consumption information of each color of printing material containers that were mounted in the printing apparatus when the printing apparatus was last powered off or before a printing material container was replaced, and the printing apparatus controller, in a case where the identification information stored in the second nonvolatile memory and the identification information read from the storage device of the printing material container that is currently mounted do not match, and second usage information that is based on the ink consumption information of each color stored in the second nonvolatile memory satisfies a predetermined condition, performs processing for additionally writing the identification information and the second usage information that are stored in the second nonvolatile memory to the first nonvolatile memory.
