Abstract: A liquid replenishing system includes a liquid tank and a liquid storage bottle for storing liquid to be replenished to the liquid tank. The liquid tank includes a tank body, a cylindrical adapter, and a needle penetrating into the tank body inside the cylindrical adapter. One end of the needle is located outside the tank body and another end of the needle is located inside the tank body. The liquid storage bottle includes a bottle body, a nozzle having an ejection port for ejecting a liquid stored in the bottle body, and includes a slit valve provided at the ejection port. In a case where the nozzle of the liquid storage bottle and the cylindrical adapter of the liquid tank are fitted to each other, one end of the needle is inserted into the slit valve so that the liquid storage bottle is secured to the liquid tank.

Abstract: A printer system connects a plurality of printers and a terminal via a network. First, the system inputs data for a new print from the terminal. Next, based on the inputted data, the system uses a learned model that has learned to select one printer among the plurality of printers based on data that was used in previous printing by the plurality of printers, to infer a printer suited to the new print from the plurality of printers. As a result of the inference, the system conveys the obtained printer to the terminal.
