An image processing apparatus includes an operation unit having a display device, and includes a sensor to detect an abnormality of the operation unit. Where the sensor detects an operation unit abnormality, display data is generated for performing display including an error notification regarding the detected abnormality. The generated display data is provided to at least one of the display device and an information processing apparatus. In a case where (i) first data for performing display includes the error notification, includes an instruction portion to receive an instruction to continuously use the image processing apparatus, and is provided as provided display data, and (ii) an instruction to continuously use the image processing apparatus is received via the instruction portion, screen data is provided, in place of the generated display data, the provided display data for displaying a screen for using an the image processing apparatus function.

Image processing apparatus, control method, and storage medium

A printing system includes at least one processor that acts as a storing unit and a determination unit. The storing unit causes history data about a print job to be stored into storage. The determination unit determines whether to cause a user to perform confirmation processing at a time of printing based on the history data about the print job that is stored in the storage.

Printing system to reduce print error in performing output processing based on data

To prevent falsification of an attribute of data, a mechanism is provided, which encrypt document/image data while holding the attribute contained in electronic document data as a plain text and make it extremely difficult to decrypt the document/image data if the attribute is falsified. A transmitter receives a public key set including a plurality of public keys from a receiver, encrypts the document/image data using a common key, selects a public key from the public key set based on an attribute of the data, encrypts the common key using the selected public key, and transmits the data including the encrypted document/image data, the encrypted common key, and the attribute to the receiver.

Information processor, information processing method and system

An image forming apparatus that is capable of accessing a removable storage medium and automatically starting an operation of calibration thereof without waiting for a user to input a job, on an as-needed basis, when a storage medium is mounted therein. A printer engine performs an image forming operation according to data read from the medium, and a controller executes calibration of the printer engine. The controller detects whether or not the medium is inserted, and determines attributes of data stored in the medium. Based on a result of determination, the controller causes the calibration to be selectively started.

A control method for controlling a printing apparatus configured to print image data and capable of conveying a printed sheet to a postprocessing apparatus configured to trim the printed sheet identifies and manages a region to be cut off by trimming and another region not to be cut off by the trimming and allows a user to easily edit an image included in the region to be cut off by the trimming. The control method includes displaying the image data, editing the displayed image data, obtaining information about a trimming position at which the postprocessing apparatus trims the sheet, and executing control for permitting editing of a first region, which is a region to be cut off by the postprocessing apparatus according to the obtained information and for restricting editing of a second region not to be cut off by trimming by the postprocessing apparatus.

This presents an image processing apparatus and an image processing method which print and output image data subjected to halftone processing with an appropriate density characteristic. The image processing apparatus generates a halftone image from a multi-value image using a threshold value arrangement, and generates a difference image between the generated halftone image and a second halftone image having the density characteristic different from that of the generated halftone image. The image processing apparatus stores the generated halftone image and the generated difference image. The image processing apparatus determines the density characteristic for printing the second halftone image, when determining to carry out printing with the density characteristic different from that of the stored halftone image, generates a halftone image by combining the stored difference image according to the determined density characteristic and the stored halftone image, and outputs the combined halftone image for printing.

A raster image processor (RIP) can process data for one page for each of a plurality of small areas, and handles each individual small area as a display list. Each individual display list holds information required to determine a rendering resolution. The RIP renders a small area including a text object with a high resolution, and a small area which does not include any text object with a low resolution. The RIP renders the respective small areas with the designated resolutions, and temporarily holds the rendering results in a memory for respective small areas. Upon generating a page image, the RIP directly transfers the high-resolution rendering result to a page memory. The RIP transfers the low-resolution rendering result to the page memory with applying an enlarging pixel process to the rendering result.

It is an object of the present invention to provide an image processing apparatus having a function to store print data in a searchable manner. In order to achieve the object, when print data including a bitmap image and attribute data of each pixel of the bitmap image is received, meta data is generated by executing a character recognition processing based on pixels having a character attribute in the attribute data. Further, vector data indicating a character outline is generated. Then, a document including meta data and vector data is generated.

An image input/output system obtains a print-job that includes printing-mode information and print-data, and analyzes the printing-mode information to determine whether the output mode of the print-data is a high-contrast output mode or a low-contrast output mode. According to the determined output mode, the image-processing device generates image data by calculating the color-space conversion of the print-data at a high bit-depth if the output mode is high-contrast, or at a low bit-depth if the output mode is low-contrast, thereby achieving output with high reproducibility in a high-contrast output mode, and high-speed output in a low-contrast output mode.

The present invention describes a process for preparing a toner mixture comprising mixing a first toner with at least one further toner wherein the first toner has an acid value of from 0.1 to 30 mgKOH/g and comprises at least one binder resin and at least one coloring agent wherein said binder comprises as the main component a polyester resin and wherein the further toners comprise at least a binder resin and optionally at least one coloring agent. It also describes a developer composition comprising said toner mixture and optionally a carrier. The new toner mixture does not show any de-mixing phenomenon during repeated use.
