A printing apparatus for storing total operation counters for individual consumable and nonconsumable parts of a printing apparatus. A nonvolatile storage retains stored count information even when power is not supplied to the printing apparatus. An operations counter counts a value indicative of a printing apparatus operation. A counter storage stores a historical counter indicative of the printing apparatus operation history to the nonvolatile storage means based on a value counted by the operations counter, and stores a total printing apparatus operations count to the storage means. Specific printer operations, such as the number of characters printed, distance of recording medium transportation, and the number of times the automatic paper cutter is operated, can thus be individually accumulated, and the historical counts, that is, the cumulative counts since the printer was first used, can be stored to memory.
