A mediation servermediates a print demand from a client deviceto a printing device. In order to elude a firewall F/W set between the mediation serverand the printing device, the printing devicefirst sends an HTTP request to the mediation server. The mediation serversends back an HTTP response including a print demand to the printing device. Encrypted communication may be established between the client deviceand the printing deviceaccording to the following procedure. The mediation serverdecrypts cipher data, which is encrypted with a public key by the client device, with a private key, re-encrypts the decrypted data with another private key, and mediates the encrypted data to the printing device. The printing devicedecrypts the encrypted data with the public key and carries out printing. This arrangement enables the printing device to carry out printing in response to a demand from the client device via respective secure network environments.
