A printing system is disclosed. The printing system includes an interpreter module to generate Tagged Object Bit-plane data corresponding to drawing objects for each colorant of a device color space during rasterization a print job data and a common buffer to store the Tagged Object Bit-plane data for each colorant.

A printing apparatus performs conversion processing that converts input data corresponding to a page into image data, executes a predetermined operation for transition of a printhead to a printing standby state, in a case where image data is delayed, performs holding processing that holds the image data in a data memory, and performs retaining processing until an amount of image data held in the data memory exceeds a predetermined amount. The printing apparatus also outputs the image data in the data memory in a case where the amount of image data held in the data memory exceeds the predetermined amount, and executes printhead printing based on the output image data. In a case where input data still remains, the conversion processing for the remaining input data is performed concurrently with the printing based on the output image data.

An image forming apparatus includes a control circuit configured to determine whether one of an x-coordinate and a y-coordinate of a path specified in each of successive drawing commands for vector objects is the same, wherein the successive drawing commands are received in incoming printable data. The control circuit is further configured to execute, when there is a new successive drawing command for a vector object in which one of an x-coordinate and a y-coordinate of the path specified by the new successive drawing command is different from the x-coordinate or y-coordinate that has been determined to be the same for previously received successive drawing commands, all of the previously received successive drawing commands having the same x-coordinate or y-coordinate.

An image forming apparatus includes a nonvolatile semiconductor storage device, a memory, and a processor. The processor is configured to exert control in such a manner that, when the nonvolatile semiconductor storage device is notified of deleted file data and a trim command is to be executed, even if an operation on file data stored in the nonvolatile semiconductor storage device is performed in the state in which the operation state of the image forming apparatus is set to the power-saving state, the trim command is not executed on the nonvolatile semiconductor storage device in accordance with the operation performed on file data.

In an example, a method includes rasterizing a seed image using a processor. A plurality of rasterized modified images may be generated from the rasterized seed image. Generating each rasterized modified image may include determining an image attribute modification and applying the determined image attribute modification to at least a portion of the rasterized seed image to generate the rasterized modified image.

An example printing method can involve a memory buffer of a printing system containing image data, and the method can include (i) issuing, by an initiator of the printing system, a single read-then-clear memory command; (ii) receiving, by a memory controller of the printing system, the single read-then-clear memory command; and (iii) in response to receiving the single read-then-clear memory command, the memory controller both (a) reading the image data from the memory buffer of the printing system and (b) after reading the image data, clearing the image data from the memory buffer of the printing system.

An apparatus including a first memory area and a second memory area is provided with a control method including specifying one or a plurality of types of image processing to be applied in the first memory area, specifying a size of obtainment target image data as a predetermined size based on a memory capacity of the second memory area and a content of the specified one or plurality of types of image processing; and obtaining first divided image data having the specified predetermined size in predetermined image data.

In an example, a method includes rasterizing a seed image using a processor. A plurality of rasterized modified images may be generated from the rasterized seed image. Generating each rasterized modified image may include determining an image attribute modification and applying the determined image attribute modification to at least a portion of the rasterized seed image to generate the rasterized modified image.

A data generating apparatus includes a controller to perform a first process to generate and store into a work area n pieces of first-layer object data representing n objects having earlier orders than a combined object in a combining sequence, a second process to generate and store into the work area M pieces of second-layer object data representing M second-layer objects of the combined object, a third process to generate first bitmap data representing an image obtained by combining the n first-layer objects, using the n pieces of first-layer object data, and a fourth process to generate second bitmap data representing the combined object. When a free space is less than a reference value during the second process, the controller interrupts the second process, performs the third process or a part of the fourth process, releases a storage area for object data, and thereafter resumes and completes the second process.

An image forming apparatus includes a nonvolatile semiconductor storage device, a memory, and a processor. The processor is configured to exert control in such a manner that, when the nonvolatile semiconductor storage device is notified of deleted file data and a trim command is to be executed, even if an operation on file data stored in the nonvolatile semiconductor storage device is performed in the state in which the operation state of the image forming apparatus is set to the power-saving state, the trim command is not executed on the nonvolatile semiconductor storage device in accordance with the operation performed on file data.
