A printing device to which a predetermined flat-rate usage fee is applied regardless of the number of times a cartridge is replaced includes an ejection head having a nozzle capable of ejecting a liquid stored in each of a plurality of cartridges, and a controller, wherein the controller includes a cleaning execution unit that executes a cleaning process and wherein the cleaning process includes a determination process of determining the presence or absence of a specific cartridge, among a plurality of cartridges, whose liquid remaining amount is equal to or greater than a reference remaining amount before performing the cleaning operation, and whose liquid remaining amount is expected to be less than the reference remaining amount when the cleaning operation is executed, and a setting process of setting the specific cartridge as a cartridge to be replaced before executing the cleaning operation.

Printing device and printing system

A liquid ejection apparatus includes a liquid ejection head configured to eject liquid from a plurality of nozzles to a medium and a plurality of caps configured to cover a plurality of nozzle groups. The plurality of caps includes a first cap group covering a first nozzle group positioned near the center of the liquid ejection head among the plurality of nozzle groups and a second cap group and a third cap group provided at positions sandwiching the first cap group in the width direction. The liquid ejection head is configured to execute a first idle ejection for ejecting liquid from the plurality of nozzles constituting the plurality of nozzle groups to the plurality of caps and a second idle ejection for ejecting the liquid from the plurality of nozzles constituting the second nozzle group and the third nozzle group to the second cap group and the third cap group.

Liquid ejection apparatus

A server apparatus includes a receiving section that receives first apparatus information and associated information in association with each other, a storage section that stores second apparatus information and user information in association with each other, a control section that determines an execution condition based on the associated information received by the receiving section, and a transmitting section that transmits, to a printing apparatus, the execution condition determined by the control section. The control section causes the execution condition thus determined and the user information associated with the second apparatus information that matches the first apparatus information to be stored in the storage section in association with each other. The transmitting section transmits, to the printing apparatus having the first apparatus information that matches the second apparatus information associated with the user information, the execution condition associated with the user information.
