Abstract
A printing apparatus () includes a slot () to and from which a memory unit () storing permitted usage amount information can be attached and removed, and a processing unit () that carries out a process for updating estimated ink amount information. The processing unit () carries out a charging process using a first memory unit (-), and in the case where a second memory unit (-) has been attached to the slot () after the charging process, the processing unit () does not carry out a charging process using the second memory unit (-) until a consumed ink amount expressed by the estimated ink amount information exceeds a prescribed threshold (WTH). The processing unit () carries out the charging process using the second memory unit (-) in the case where the consumed ink amount has exceeded the prescribed threshold (WTH).
