A color printing device can include a print engine, a circuit, and a processor. The print engine prints onto physical media using different color colorants. The circuit has data-processing color channels corresponding to the different color colorants. The processor receives monochromatic print jobs and transmits the received monochromatic print jobs to unused color channels of the color channels for processing in parallel. The processor can transmit the processed monochromatic print jobs to the print engine for printing.

Provided by the present disclosure are a method and an apparatus for printing a relational graph. The method for printing a relational graph includes: determining whether an overall view of a to-be-printed relational graph exceeds a set print size; in response to the overall view of a to-be-printed relational graph exceeding the set print size, clustering nodes in the to-be-printed relational graph according to the print size and attribute information of the nodes to form a clustered overall view of the relational graph and subviews of the relational graph; and printing the clustered overall view of the relational graph after the clustering and subviews formed based on the clustered nodes. At least one embodiment of the present disclosure can automatically split a relational graph into pages for printing.

Strips of a page are processed according to a rendering technique, compressed, and stored in a memory buffer until a low memory condition of the buffer occurs. When the low memory condition occurs, the strips that are already stored in the buffer are decompressed, processed according to a memory utilization reduction technique, compressed, and stored in the memory buffer. Strips that are not yet already stored in the buffer when the low memory condition occurs are processed according to the rendering technique and then according to the memory utilization reduction technique before being compressed and stored in the memory buffer.

An image forming apparatus includes circuitry to receive a file including data of a plurality of pages and position information indicating individual positions of data of the plurality of pages. The circuitry further starts printing of one of the plurality of pages based on data specified by specifying information that indicates a position of data of one of the plurality of pages. The circuitry further starts the printing of one of the plurality of pages when receiving the specifying information before the position information.

An information processing apparatus includes: an assignment unit that assigns plural associated execution instructions to a first group and a second group; and an order setting unit that sets an order of second execution instructions assigned to the second group in accordance with an order of first execution instructions assigned to the first group.

A printing system, a non-transitory recording medium, and a print control method. The printing system adds a command for instructing printing with special color material to a single color page in first print data, the first print data having been generated based on image data including the single color page in which an object is drawn in single color, transmits to the image forming apparatus, second print data that has the command added, and prints the single color page in the second print data with the special color material.

A print control system that outputs a video signal to a printer, includes: a plurality of print controllers including a first print controller and a second print controller. The first print controller is connected to a printer and includes an administrator that acquires a print job comprising image information, divides the image information of the acquired print job, and distributes the divided image information to the first print controller and the second print controller; and a first RIP processor that generates image data by rasterizing the image information distributed to the first print controller. The second print controller includes a second RIP processor that generates the image data by rasterizing the image information distributed to the second print controller.

Provided is an image forming apparatus capable of executing a copy job without causing a memory shortage by dividing and sequentially executing the copy job process. The image forming apparatus includes a free area determining unit and a division process executing unit. The free area determining unit compares capacities of work areas necessary for executing a scanning job and a printing job with free area in memory (RAM), respectively. The division process executing unit, in a case where the free area determining unit determines that the free area in memory is equal to or greater than the capacity of the work area necessary for executing the scanning job, but is less than the capacity of the work area necessary for executing the printing job, cancels parallel processing, and after executing the scanning process, saves in a non-volatile memory, and then after restarting, executes the printing process.

A printing apparatus acquires change history information indicating a print setting value of a print setting item has been changed in accordance with received change instructions, with the print setting item being a print setting item that has not been able to be set for the print job selected from a list by an external device having transmitted the print job to the printing apparatus, and displays recommended settings that are print settings determined based on the acquired change history information about the selected print job. A print setting value of a print setting item of a print job selected from the list is changed based on a selection of the displayed recommended settings, and the selected print job is executed by using print setting values including the print setting value that has been changed in accordance with the received change instruction.

Provided is a technique that enables efficient setting of poster printing and efficient processing of an image. To this end, a control apparatus of the present invention is a control apparatus that allows a printing apparatus to print multiple divided images, into which an input image is divided, on print media, including: a setting unit that sets the number of divisions of the input image based on user input; an obtaining unit that obtains a width of the print media; a determining unit that determines a scale factor of the input image based on at least the set number of divisions, the width of the print medium, and a width of the input image; and a display control unit that displays a preview screen of the input image and a processing instruction item for instructing processing of the input image together, in which in a case where processing of the input image is instructed by user operation through the processing instruction item, the display control unit displays a processed input image reflecting the processing based on the processing instruction, and the determining unit determines a scale factor of the processed input image based on a width of the processed input image.
