An information processing system includes a generation unit and a reconstruction unit. The generation unit generates a data source including data to be referred to at a time of printing for a variable portion in which data to be referred to is variable for each record. The reconstruction unit acquires the data source and reconstructs print data that is variable for each record. The generation unit executes processing of determining a largest size based on a size of data to be referred to for the variable portion to generate stub data of the determined size, of generating the print data by using the stub data, and of generating the data source for each record. The reconstruction unit executes processing of reconstructing the print data by overwriting the stub data in the print data with the data in the acquired data source.

Information processing system, information processing apparatus, information processing method, and storage medium

A processing apparatus includes a generation unit configured to generate print data that is based on a print job, an identification unit configured to identify a preparation time necessary for preparing the print data to be generated by the generation unit, a prediction unit configured to predict a permitted time permitted until preparation of second print data to be printed after first print data is printed is completed on the basis of a preparation time necessary for preparing the first print data, a reception unit configured to receive a supply request for the print data when printing is to be carried out by a printing unit, and a determination unit configured to determine whether print data of a predetermined unit including the second print data generated by the generation unit is to be stored in a print data storage unit.

Processing apparatus and processing method for processing print jobs

An electronic device comprises: a management unit configured to manage device information of the electronic device by storing the device information in a first storage unit; a communication unit configured to communicate with an external device according to short distance wireless communication; a storage control unit configured to control, when the electronic device transits from a power-on state to a power-off state, to write the device information stored in the first storage unit in a second storage unit; and a control unit configured to control, upon receiving a read request or write request of the device information from the external device via the communication unit, to read or write the device information stored in the second storage unit when the electronic device is in the power-off state.

Electronic device and method for printing based on information written by an external device in a power-off state

A printing apparatus sequentially prints a plurality of images on a first surface of a sheet, and then sequentially prints a plurality of images on a second surface that is a back surface of the first surface. When a state of a printing unit is determined not to be normal when printing on the first surface, the printing apparatus executes processing for maintenance by using a sheet different from the sheet used for printing on the first surface.

Printing method and printing apparatus for printing a plurality of images on a sheet using a print head

A state of a print head is checked by printing a plurality of images in order on a sheet fed from a sheet feeding unit, and reading the printed images. A region that is inappropriate for performing printing on the fed sheet is detected. When the inappropriate region has been detected, printing the images is stopped and the sheet is cut. Of the cut sheets, the sheet at an upstream is sent back to the sheet feeding unit. Subsequently, the sheet is again fed to perform printing and conduct a test.

A print control apparatus configured to cause a printing unit to perform print processing includes a determination unit configured to determine whether a condition for executing maintenance processing of the printing unit is satisfied, a shortening unit configured to shorten redundant maintenance operations in first maintenance processing and second maintenance processing in a case where the determination unit determines that a condition for executing the second maintenance processing is satisfied before completion of the first maintenance processing, and a control unit configured to cause the first maintenance processing and the second maintenance processing to be carried out after the shortening unit shortens the redundant maintenance operations.

Print control apparatus, print control method, and recording medium

An information processing apparatus that performs mapping of a data field in a database to a document template holding a variable area according to a mapping rule defined in the variable area, thereby generating print data for each record in the database, the information processing apparatus comprises: an accepting unit configured to accept designation from a user regarding whether or not to perform encryption of the data field referred to by the mapping rule, for each data field; a determination unit configured to determine whether or not to encrypt content that is to be applied to the variable area based on the data field for which encryption designation is accepted by the accepting unit and the mapping rule; and a generation unit configured to encrypt the content that is to be applied to the variable area and that is determined to be encrypted by the determination unit.

Information processing apparatus, control method and computer-readable medium

An information processing apparatus includes an automatic update determination unit that stores update information for updating a record level among layers included in print data, a layered metadata change unit that acquires a key included in metadata in the print data and a value corresponding to the key, generates a change screen that can receive an instruction relating to grouping processing of the metadata, performs grouping processing on the metadata based on the instruction relating to grouping processing received via the change screen, determines based on the update information whether the record level needs to be changed by the grouping processing, and changes the record level when it is determined that the record level needs to be changed.

Information processing apparatus, information processing apparatus control method, and storage medium

A GUI generation apparatus comprises: a storage unit adapted to store association information that associates an input/output GUI component relating to the input and output of data with a data model that stores data; and a reflection unit adapted to, upon receiving an input of data through the input/output GUI component, reflect the inputted data in the data model that is associated with the input/output GUI component in the association information, wherein, upon a change of data in the data model, the reflection unit reflects the changed data in the input/output GUI component that is associated with the data model in the association information.

GUI generation apparatus and method for generating GUI

A recording apparatus includes a recording unit configured to record moving image data including a plurality of frames on a recording medium. The recording medium includes a plurality of clusters. The apparatus also includes an editing unit of the moving image data, a setting unit configured to optionally set the editing unit, a management information processing unit configured to generate management information including link information indicating a cluster number of the moving image data to be reproduced next with respect to a plurality of clusters having the moving image data recorded thereon, and a control unit configured to control the recording unit to record a front frame of each editing unit in the moving image data on an area beginning with a cluster of the recording medium based on the editing unit set by the setting unit.

Recording apparatus for recording data to recording medium with a Plurality of clusters

This invention provides a technique that deletes data at high speed, and prevents discontinuous cluster chains from being produced due to data deletion. To accomplish this, when data included in the data file is partially deleted from the head of the data file, the location of header information is moved for respective clusters, and the size of the header information is changed, so as to start head data after data deletion from the location immediately after the moved header information.
