Abstract: An information processing apparatus includes a storage that stores a machine-learned model, an accepting section, and a processor. In the machine-learned model, machine learning has been performed according to a data set in which failure state information about a print head, use environment information about a printing apparatus, and action information representing a recommended action are associated. The accepting section accepts the failure state information about the print head and the use environment information. The processor suggests an action matching the failure according to the machine-learned model and the accepted failure state information and use environment information.

Abstract: In a system in which a server and a client to which a device is connected communicate, the server can execute processes based on the result of checking device operation. The POS terminal of a network system has a device control function for controlling the device, and a diagnostic function for checking operation of the device. To check the operation of the device connected to the client, a maintenance server sends a control command instructing starting the diagnostic function to the POS terminal. The POS terminal stops the device control function if the device control function is executing, starts the diagnostic function, checks operation of the device with the diagnostic function, and returns the result of the checked operation to the maintenance server.
