The contents provider comprises a device for generating viewing screens, a device for generating a conditions settings screen from printout information and service information obtained from a printout service provider, a device for generating a confirmation screen for setting the conditions, and a device for transmitting the contents selected with the viewing screen, and the printout service provider comprises a device for transmitting the service information, and a device for generating printing data from the contents provided from the contents provider. This provides contents providers with contents providing means other than downloading data, and users with services for various printing forms other than home-use printers.
