Provided is an image forming apparatus including: an obtainment unit configured to obtain print data including drawing commands; a first image processing unit configured to perform conversion of color information for drawing an object having a non-image attribute among objects to be drawn by the drawing commands; a command execution unit configured to generate raster image data based on the drawing commands; a storage configured to store the generated raster image data to perform predetermined output; a second image processing unit configured to perform conversion of color information on an object having a picture attribute in the generated raster image data; and a control unit configured to perform the predetermined output in a case where a predetermined condition is met.

A printing apparatus includes a conveyance unit including a pair of rotation members that nip a roll sheet, and configured to convey the sheet by rotation of the pair of rotation members, a printing unit, and a control unit configured to, upon executing a new print job, cause the conveyance unit to perform a preparatory operation in which the sheet is conveyed in a forward direction and then conveyed in a reverse direction and stopped. If a predetermined condition is met after completion of a previous print job, the control unit causes the conveyance unit to perform the preparatory operation, and if the predetermined condition is not met after completion of a previous print job, the control unit does not cause the conveyance unit to perform the preparatory operation.

An image processing device includes an input device and circuitry. The input device inputs data. The circuitry converts text information to be printed included in the data to generate converted information and outputs data for image formation including the converted information.

In a print data editing device, controller is configured to perform: editing; and converting. The editing edits print data representing an input image such that when sub-dots constituting the input image are compared by units of columns before and after performing the editing, a coincidence is maximized when an image of each column in the input image after the editing is the same position as an image of the corresponding column in the input image before the editing or is shifted by a corresponding shift amount in a sub-scanning direction relative to the image of the corresponding column in the input image before the editing. The converting includes: determining one or more sub-dot as a conversion sub-dot; and editing the print data such that the print data indicates OFF for the one or more sub-dots determined as the conversion sub-dot.

A print data editing device performs editing print data such that when dots constituting an input image represented by the print data are compared by units of columns before and after performing the editing, a coincidence is maximized when an image of each column in the input image after the editing is the same position as an image of the corresponding column in the input image before the editing or is shifted by a corresponding shift amount relative to the image of the corresponding column in the input image before the editing and an editing condition is met. The editing condition includes that an absolute value of at least one shift amount is one dot or greater, an absolute difference value for any two neighboring columns is one dot or less, and at least one absolute difference value for all possible combinations of two columns is less than one dot.

A method of processing linearized and non-linearized Portable Document Format (PDF) files for printing comprises: determining by printer firmware if a printer driver detected that the PDF file is linearized; saving stream data of the PDF file by the printer firmware when the printer firmware determines the printer driver detected that the PDF file is linearized; and determining by the printer firmware if the PDF file is linearized when the PDF file is unidentified as being linearized by the printer driver, wherein the printer firmware identifies real and false linearization error during linearized processing and identifies and processes printing errors in a parallel manner during saving and interpreting stream data.

An information processing device includes an information acquisition unit that acquires at least one of attribute information of image data to be image processed and setting information related to the image process on the image data, and a prediction unit that predicts, based on a machine-learned model that accepts input of at least one of the attribute information and the setting information to output a period required for the image process, a period required for the image process on the image data from information acquired by the information acquisition unit.

An image forming system for printing a sequence of image blocks on a continuous printing sheet based on image data, includes an information processing apparatus and an image forming apparatus. A printing setting unit included by the information processing apparatus designates first information and second information. The first information indicates whether a printing order of the image blocks is to be a normal order or a reverse order. The second information indicates how many image blocks of the sequence are to be printed on each of a plurality of segments of the printing sheet. The image forming apparatus includes a cutting unit and a control unit. The cutting unit cuts the printing sheet. The control unit controls the cutting unit so as to separate the segments of the printing sheet. The control unit determines cutting positions on the printing sheet based on the first information and the second information.

A print control device is provided with a management unit that receives and manages an instruction to execute processing, a processing unit that performs processing based on the instruction that is received, and a storage unit that stores an attribute information indicating an attribution of the instruction stored by the management unit and state information indicating a processing state of the processing unit in a nonvolatile storing unit using resources of the processing unit when processing based on the instruction is not executed.

A printing apparatus includes a first interpretation unit configured to generate intermediate data of a page by interpreting print data, a second interpretation unit configured to generate intermediate data of another page by interpreting the print data, and a controller configured to perform, according to a specific print setting command indicating that a specific process is to be performed on all pages, control such that the specific process is performed on all the pages. The controller performs the control if the specific print setting command is included in a specific page.
