Abstract: A printer selects time-series data satisfying a condition indicating that the printer is active as input data from among time-series data obtained from a sensor. A cloud server generates a learning model that has learned to output a prediction value corresponding to a second time as output data in a case where input data until a first time is input based on the input data until the first time and teacher data that is sensor data at a second time after the first time.

Abstract: A printing apparatus that replenishes ink by exchanging an exchange ink tank includes a code reader for inputting ink information representing an ink type, a float sensor for detecting that the exchange ink tank has changed to an empty state, and a main controller. The main controller determines that the exchange ink tank can be exchanged if the float sensor detects that the exchange ink tank is in the empty state, and if first ink information associated with the exchange ink tank and second ink information associated with an installation location of the exchange ink tank, which are input by the code reader, are compared, and it is determined that the first ink information and the second ink information are compatible.
