摘要:
A server computer searches for at least one printing-service providing store based on printing-condition information sent form an information terminal, and sends information representing the searched printing-service providing store to the information terminal. After a user selects one printer device based on the information representing the at least one printing-service providing store, the information terminal sends document data to be printed to the server computer. The server computer sends printing data to be printed to the user-selected printer device.
