ABSTRACT:
A remaining amount detecting step is performed by a first controller, in which a remaining amount of a liquid contained is detected for each of a plurality of cartridges containing the liquid to be ejected from nozzles. An information transmitting step is performed by the first controller, in which when the remaining amount of the liquid in at least one of the cartridges is detected to be equal to or lower than a predetermined amount, information relating to a cartridge with a small remaining amount is transmitted, the cartridge with the small remaining amount corresponding to the at least one of the cartridges. A liquid ejection data generating step is performed by a second controller, in which at least one cartridge other than the cartridge with the small remaining amount is determined as a substitute cartridge based on the information, relating to the cartridge with the small remaining amount, that has been transmitted, and liquid ejection data for controlling ejection of the liquid contained in the substitute cartridge is generated and transmitted. The remaining amount information obtaining step is performed by the second controller, in which information relating to a remaining amount of the liquid of the substitute cartridge is obtained from the first controller each time a process of transmitting the liquid ejection data is performed, after the information relating to the cartridge with the small remaining amount has been received.
