Abstract: An information processing apparatus that transmits a plurality of parameter values of a device to an external apparatus includes a first transmission section that selectively periodically transmits the plurality of parameter values or part of the plurality of parameter values, and a second transmission section that transmits the plurality of parameter values to the external apparatus, in a case where an amount of change in a predetermined parameter value included in the part of the plurality of parameter values satisfies a predetermined condition in a period between a previous periodic transmission and a current periodic transmission, after the predetermined condition is satisfied and before the current periodic transmission is performed.

Abstract: When a problem occurs in a subset of devices, another device appropriately executes a process instead of the problem device. A printer has a decision unit that determines whether or not a request for specific information was received at a specific time from a specific printer; an information collection device that, when the request is not received at the specific time, collects the specific information of each printer from other printers capable of communicating; and an information transmission device that transmits the specific information that was collected and the specific information about the printer of which it is part to an external server.

Abstract: A charge calculation apparatus includes: a consumed amount acquisition section that acquires an amount of a consumable consumed for printing in a first period; a carried-forward amount calculation section that calculates a carried-forward amount of the consumable on a basis of the consumed amount and a base amount of the consumable for the first period; and a charge calculation section that calculates an amount of money charged for printing on a basis of the carried-forward amount. The consumed amount acquisition section acquires a second consumed amount that is an amount of the consumable consumed for printing in a second period that is posterior to the first period. The charge calculation section calculates the amount of money charged for the second period on a basis of the second consumed amount, a second base amount that is a base amount of the consumable for the second period, and the carried-forward amount.
