When information on remaining amount of toner is successful, a printing apparatus notifies a management server with identification information of the toner bottle and information on remaining amount of toner, obtains toner usage amount used in printing processing according to an execution of printing processing based on print job, and updates information on remaining amount recorded in the IC chip according to usage amount. When reading of information of the IC chip fails, updating of information on remaining amount recorded in the IC chip, according to usage amount of toner used in printing processing according to execution of printing processing based on print job, which is received when the reading fails, is suppressed. Notification including information indicating the reading has failed as the information on remaining amount is transmitted. ## Claims ### Claim 1 A printing apparatus equipped with a consumable item including a recording agent used in the printing apparatus, the printing apparatus comprising: a memory storing instructions;
