A license management server manages a license to perform a service of remote maintenance related to one or more image forming apparatuses installed in a customer's site. The maintenance server includes a maintenance unit and a history management unit. If the license management server notified of expiration of an expiration date of the license defined by a contract, the maintenance unit stores history information acquired from the one or more image forming apparatuses corresponding to the expired license into a storage unit, and stops the service. If the license management server notified of grant of the license by a re-contract, the history management unit obtains the history information about the one or more image forming apparatuses corresponding to the granted license from the storage unit, and passes the obtained history information to the maintenance unit. By using the passed history information, the maintenance unit resumes the service.

A mobile printing system includes a cloud server apparatus, a mobile terminal device, a device management server apparatus, a print-control device, and an image forming apparatus. The cloud server apparatus stores a document data file. The mobile terminal device includes a wireless communication interface, and a short-range communication interface of which the maximum communicable distance is shorter than that of the wireless communication interface, and transmits the document data file with its device ID to the cloud server apparatus. The device management server apparatus receives the document data file in association with the device ID, and converts the document data file to print data and stores it. The print-control device detects the mobile terminal device using a short-range communication interface, and receives its device ID, and receives the print data from the document management server apparatus, and transmits the print data to the image forming apparatus for printing.

Mobile printing system using a device management server

A method for secure communication and printing, comprising: user entering user and destination information to host; authentication server producing, saving encryption key for the job, user, and destination information into database, and sending to host; host encrypting the job using encryption key and sending job to destination; user entering user and destination information to device; authentication server retrieving encryption key from database, and sending to device; and device decrypting the job using encryption key and releasing job. Authentication at both host and MFP sides disables unauthorized, malicious attack to a user's mailbox, and results in jobs to a mailbox having different dynamic encryption keys, and no password or mailbox PIN trafficking on network. Furthermore, host and MFP can be at different domains. Methods also include secrecy encrypting encryption key; hashing key generator using SHA1, MD5, etc.; password, PIN, RFID, biometrics; and timer module deleting jobs older than threshold value from storage.
