Print data management apparatus, storage medium having stored therein print data management program, storage medium having stored therein usage certificate data, and method of using print data

摘要

The invention provides a print data management apparatus which can use print data advantageously in terms of data capacity. A database server performs a registration process and a providing process. When a data registration request is received from a shop, the registration process registers receipt data included in the received data registration request in association with data name information, password information, and the like. At the same time, the registration process transmits usage certificate data which includes the information and to a buyer. When a data usage request is received from a print server, and when a password of a record in which the same data name as that included in the received data usage request is registered matches a password included in the received data usage request, the providing process transmits receipt data specified by the data name included in the received data usage request to the print server.
