Information-processing apparatus capable of generating screen data representing settings screen on which reference value for index value is inputted

A non-transitory computer-readable storage medium storing a set of program instructions for an information-processing apparatus for managing a print executing unit, the print executing unit including:

• an attachment portion to which a cartridge storing printing agent is attachable;
• a container for receiving the printing agent from the cartridge attached to the attachment portion and storing the received printing agent;
• and a printing mechanism configured to perform printing operations using the printing agent stored in the container,
• the information-processing apparatus comprising a processor, the set of program instructions, when executed by the processor, causing the information-processing apparatus to perform:
• (a) generating screen data representing a settings screen, the settings screen being for setting a reference value on the basis of a user instruction, the reference value and an index value for a total residual quantity being compared with each other to determine whether a replenishment condition is met, the total residual quantity being a total quantity of a first residual quantity and a second residual quantity, the first residual quantity being a quantity of printing agent remaining in the cartridge, the second residual quantity being a quantity of printing agent remaining in the container, a notification triggering replenishment of the print executing unit with printing agent being made when the replenishment condition is met;
• and
• (b) outputting the generated screen data,
• wherein the settings screen includes:
• an indication of a specific range of possible values for the index value;
• an indication of a value designated from the specific range as the reference value by the user instruction;
• and
• an indication of a boundary value, the boundary value being a value within the specific range and corresponding to a boundary quantity, the boundary quantity being the total residual quantity at a time of transition from a first state to a second state, the first state being a state in which the printing agent remains both in the cartridge and in the container, the second state being a state in which the printing agent vanishes from the cartridge but remains in the container.
