When cartridge replacement has occurred, reference use information that is acquired for the first time after occurrence of the cartridge replacement and reference time information indicative of when the reference use information is acquired are stored. Every time target use information, which is acquired after the reference use information is acquired, is acquired, a first period, which is defined from a particular time until printing by a printing execution section using printing agent in a presently-connected cartridge is estimated to become impossible, is computed based on the target use information, target time information indicative of time when the target use information is acquired, the reference use information, and the reference time information. When the first period is shorter than a first set period, output information corresponding to the state of use of the presently-connected cartridge is outputted. |

1. A non-transitory computer readable storage medium storing a set of program instructions for a control device, the program instructions, when executed by a computer provided in the control device, causing the control device to perform:
repeatedly acquiring use information indicative of a state of use of a cartridge that is presently connected to a connection section so as to be used by a printing execution section, the cartridge being configured to accommodate printing agent therein, the printing execution section being configured to execute printing by using the printing agent accommodated in the presently-connected cartridge; acquiring specific information from a supply source of the acquired use information, the specific information being used for determining whether cartridge replacement has occurred; determining, by using the acquired specific information, whether cartridge replacement has occurred; when it is determined that cartridge replacement has occurred, storing in a storage section reference use information and reference time information in association with each other, the reference use information being such use information that is acquired for the first time after the cartridge replacement has occurred, the reference time information being indicative of time when the reference use information is acquired; every time when target use information is acquired, computing a length of a first period, the target use information being such use information that is acquired after the reference use information is acquired, the first period being defined as a period of time defined from a particular time until printing by the printing execution section using the printing agent in the presently-connected cartridge is estimated to become impossible, the length of the first period being computed based on the target use information, target time information, the reference use information that is stored in the storage section, and the reference time information that is stored in the storage section, the target time information being indicative of time when the target use information is acquired; and when the length of the first period is shorter than a length of a first set period, outputting output information corresponding to the state of use of the presently-connected cartridge. |
