A printing system is constructed by connecting a management server with a large number of printers via a network. Each printer records a log, which represents a consumption of an expendable, for example, a consumption of toner, and is mapped to an elapsed time period measured by a built-in timer, and uploads the recorded log to the management server at a preset cycle. The printer acquires an upload time from the management server in the process of uploading and carries out subsequent recording with the acquired upload time as a base time. The printer corrects the elapsed time period mapped to the log, based on the upload time acquired from the management server. This arrangement enables even a printer without a real time clock to prevent expansion of an error and efficiently record the log with high accuracy. <IMAGE> |
