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 that is information for estimating an amount of the ink in an ink holding unit. When the 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 memory unit, on the basis of a process for determining whether or not consumed ink amount expressed by the estimated ink amount information exceeds a prescribed threshold (WTH). The processing unit executes forced charging process that executes the charging process in the case where there is an instruction from an operator of the printing apparatus before the prescribed threshold WTH is exceeded.
