Abstract
A controller determines, for each cartridge, whether a remaining amount in a first liquid chamber is smaller than a first liquid amount; in response to determining that a first cartridge exists for which the remaining amount is smaller than the first liquid amount, determines, for each cartridge other than the first cartridge, whether the remaining amount is smaller than a second liquid amount larger than the first liquid amount; in response to determining that a second cartridge exists, determines whether a remaining amount of the second cartridge is smaller than the first liquid amount, the second cartridge having the remaining amount smaller than the second liquid amount; and in response to determining that a particular second cartridge exists, displays a first screen including a first object that prompts replacement of the first cartridge and the particular second cartridge having the remaining amount smaller than the first liquid amount.
