Printing apparatus
First Claim
1. A printing apparatus comprising:
- a slot to and from which a memory unit storing permitted usage amount information of ink held in an ink holding unit can be attached and removed; and
a processing unit that carries out a process for updating estimated ink amount information that is information for estimating an amount of the ink in the ink holding unit,wherein in the case where a first memory unit is attached to the slot, the processing unit carries out a charging process that updates the estimated ink amount information using the permitted usage amount information in the first memory unit; and
in the case where a second memory unit is attached to the slot after the charging process, the processing unit does not carry out the charging process using the second memory unit until a consumed ink amount expressed by the estimated ink amount information exceeds a prescribed threshold, and in the case where the consumed ink amount has exceeded the prescribed threshold, the processing unit carries out the charging process using the second memory unit.

Abstract
A printing apparatus (200) includes a slot (230) to and from which a memory unit (100) storing permitted usage amount information can be attached and removed, and a processing unit (210) that carries out a process for updating estimated ink amount information. The processing unit (210) carries out a charging process using a first memory unit (100-1), and in the case where a second memory unit (100-2) has been attached to the slot (230) after the charging process, the processing unit (210) does not carry out a charging process using the second memory unit (100-2) until a consumed ink amount expressed by the estimated ink amount information exceeds a prescribed threshold (WTH). The processing unit (210) carries out the charging process using the second memory unit (100-2) in the case where the consumed ink amount has exceeded the prescribed threshold (WTH).
