Abstract: Provided is technology enabling uploading device management information more appropriately. A communication device that manages a device, including: a storage device configured to store management information related to the device; a communicator configured to execute communication with an external device through a network; and a controller configured to cause the communicator to send the management information to a server specified by address information as the transmission destination when the communicator receives from a management server address information specifying a server to manage the device. The controller causes the communicator to send device identification information to the management server; and the communicator receives the address information corresponding to the identification information from the management server as a response to transmission of the identification information.

Abstract: A server includes: a communication unit that performs communication via a network; a storage unit that stores association information in which identification information on a device that utilizes consumables is associated with purchase source information indicating a purchase source from which the consumables are to be purchased; and a control unit that, when the communication unit receives identification information, causes the communication unit to transmit window information used for purchasing the consumables from a purchase source indicated by the purchase source information associated with the received identification information in accordance with the association information.

Abstract: A consumable management server connectable to a network includes a management section that manages identification information of a device using a consumable and supplier information indicating a supplier of the device in association with each other, a consumable information acquisition section that acquires consumable information on the consumable of the device through the network, and a delivery request processing section that transmits a delivery request for the consumable to the supplier through the network based on the supplier information associated with the identification information of the device in a case where the consumable is determined to be in a state of requiring replacement based on the consumable information.
