Abstract
A printer module for giving notification of the status of the printer receives a request from a host to the effect that the host be registered as the destination of printer-status notification. The printer module responds by registering the host as a printer-status notification destination in a notification-destination registration table. The registered information includes registration retention time. A time-out module in the printer deletes registration, for which the retention time has expired, from the notification-destination registration table.
