Print job data is generated in accordance with a printing instruction from an application. When encryption of the print job data is designated, the generated print job data is encrypted, and the generated or encrypted print job data is output. When a printing apparatus serving as an output destination to which the encrypted print job data is output does not have a decryption function of decrypting the encrypted print job data, the output destination is changed to a decryption apparatus having the decryption function. When designation to save the print job data in the printing apparatus is detected in encryption, the print job is canceled.

Information processing apparatus that does not transmit print job data when both encryption and saving in a printing apparatus are designated, and control method and medium therefor

A technique for providing a first information processing apparatus configured to acquire first identification information as information for identifying the information processing apparatus, searching for a second information processing apparatus capable of wireless communication, acquiring a second identification information as information for identifying the second information processing apparatus that was found, comparing the first identification information and the second identification information, changing the first identification information when the first identification information and the second identification information are identical, and notifying when the first identification information is changed.

Information processing apparatus and method for wireless communication with other information processing apparatuses

A print system which are capable of inhibiting simultaneous use of the encrypted print and the box storage to thereby increase the security of print data. A host computer has an encryption function of encrypting print data, and issues a print job for the print data encrypted by the encryption function. A print server receives the issued print job, and has a decryption function of decrypting the encrypted print data of the received print job. A printer has a storage function of storing the print data decrypted by the decryption function, and outputs the stored print data. At least one of the host computer and the print server inhibits simultaneous use of the encryption function and the storage function.

When a user logs in and inputs document data into a box, a usage history of the box as used by the user is determined by referring to a user information management table. If there is a record, process attributes are set, and a process associated with the box is executed. If there is no record, a message indicating that there is no record is displayed. If execution is selected in response to this display, the process is executed. Once the process has ended, the usage record of the box as used by the user is updated to 'used'.

Information processing apparatus that controls transmission of print job data based on a processing designation, and control method and program therefor

An information processing apparatus connected to a printing apparatus via a network encrypts print data if identification information is input, and does not encrypt print data if identification information is not input. If identification information is input and the print data has been encrypted, the information processing apparatus sends a print job including the encrypted print data to the printing apparatus via the network; otherwise, the information processing apparatus sends unencrypted print data to the printing apparatus via the network.

Information processing apparatus connected to a printing apparatus via a network and computer-readable storage medium having stored thereon a program for causing a computer to execute generating print data in the information processing apparatus connected to the printing apparatus via the network

In an image forming method of receiving encrypted data generated by an information processing apparatus, decrypting the encrypted data into data to be printed, and causing an image forming apparatus to execute printing processing, print data is acquired by decrypting the received encrypted data, and the acquired print data is converted into image data for which the printing processing can be performed. The image data is encrypted with first key information.

Image forming apparatus, image forming method, information processing apparatus and information processing method

A data processing device transmits specific information through a network, receives a public key transmitted based on the specific information through the network, and stores the received public key. Further, the data processing device receives print data and encrypted data corresponding to the print data, decrypts the received encrypted data by using the stored public key, and prints the received print data if the data after it was decrypted is specific data. Meanwhile, the data processing device does not print the received print data if the data after it was decrypted is not the specific data.

Data processing device, information processing device, and data processing system

In order to maintain high security of a job that requires a high security level even after a print interrupt factor has been removed, and to achieve both the effect of maintaining high security of a job that requires a high security level even after the print process is interrupted, and the effect of improving the productivity of jobs other than a job of this type, when a print apparatus which can process a plurality of print jobs including a print job of a first type and that of a second type restarts a print operation of a print job, which is interrupted in the print apparatus, and when the print job is a print of the first type, the print apparatus is controlled to execute an authentication process, and then allowed to restart the print operation of the print job. When the print apparatus restarts a print operation of a print job, which is interrupted in the print apparatus, and when the print job is a print of the second type, the print apparatus is allowed to restart the print operation of the print job without executing the authentication process.

Print job authentication

A client server system which enables the user of a client computer to obtain the optimum printing result only by designating desired print settings, and to perform printing according to common print settings even if printers are modified or a new printer is added on a network. A favorite display module displays a print setting designating screen relating a printer. A data sending and receiving module transmits the print settings designated on the print setting designating screen by a user and an ID of a client computer to a server. A data sending and receiving module receives a printer driver adapted to the printer and print setting information from the server. A favorite setting changing module changes print settings of the printer driver according to the print setting information sent from the server. A favorite setting completion display module indicates that the changing of the print settings has been completed.
