NETWORK PRINTING SYSTEM AND NETWORK PRINTING PROGRAM

摘要

A desired printer can be reliably selected and the setting of which printer is permitted to communicate with which mobile terminal can be easily altered. A mobile terminal acquires printer identification information from a printer by NFC communication, and transmits the printer identification information and mobile terminal identification information to a server, thereby requesting an authentication. The mobile terminal transmits print data to the printer to instruct a printing execution when the authentication is successful. Therefore, the desired printer can be reliably selected by placing the mobile terminal close to the desired printer. Any stolen mobile terminal can be disabled for any printer only by rewriting the centrally managed information on the server.

主权项

1. A network printing system comprising a server, a mobile terminal, and a printer connected to each other through a communication network:
wherein the printer comprises a printer identification information storage unit configured to store printer identification information for identifying the printer, wherein the mobile terminal comprises:
a mobile terminal identification information storage unit configured to store mobile terminal identification information for identifying the mobile terminal;a printer identification information acquiring unit configured to acquire the printer identification information stored in the printer identification information storage unit of the printer;an authentication request unit configured to request an authentication to the server by transmitting the mobile terminal identification information read from the mobile terminal identification information storage unit and the printer identification information acquired by the printer identification information acquiring unit;an authentication determination unit configured to determine whether the authentication is successful based on an authentication result returned from the server in response to the authentication request by the authentication request unit; andupon determining that the authentication is successful by the authentication determination unit, a printing execution instruction unit configured to transmit print data to the printer whose printer identification information is acquired by the printer identification information acquiring unit, and wherein the server comprises:
a matching information storage unit configured to store the printer identification information of the printer in association with the mobile terminal identification information of the mobile terminal permitted to communicate with the printer; andupon receiving the authentication request from the authentication request unit of the mobile terminal, an authentication processing unit configured to perform the authentication by comparing the mobile terminal identification information and the printer identification information transmitted from the mobile terminal with the mobile terminal identification information and the printer identification information stored in the matching information storage unit, and to return the authentication result to the mobile terminal.
