摘要： Provided is an image processing apparatus including a print image generation section that generates print image data to be supplied to a printing device by executing a rasterizing process and an additional process for printing on print data, and an image density calculation section that executes the rasterizing process on the print data without the additional process and calculates image density information used in control of an image forming process in the printing device from raster image data generated through the rasterizing process to process the print data at a speed higher than a speed in print image generation section, wherein a difference in a processing speed between the print image generation section and the image density calculation section causes image density information of a page prior to a page of the print image data printed by the printing device to be supplied to the printing device.

摘要： Provided is an image processing apparatus including a print image generation section that generates print image data to be supplied to a printing device by executing a rasterizing process with a resolution for printing on print data, and an image density calculation section that executes the rasterizing process on the print data with a resolution lower than the resolution for printing and calculates image density information used in control of an image forming process in the printing device based on raster image data which is generated through the rasterizing process and has a resolution lower than the resolution for printing, wherein a difference in a processing speed between the print image generation section and the image density calculation section causes the image density information of a page prior to a page of the print image data being printed by the printing device to be supplied to the printing device.

摘要： An image processing apparatus includes a converter, a reuse portion storage unit, and a reuse information output unit. The converter converts page description language (PDL) data into printable data. The converter stores a conversion result of converting an object appearing in the PDL data multiple times into printable data in a storage device and reuses the conversion result for the object which appears after the conversion result has been stored, instead of converting the object into printable data. The reuse portion storage unit stores information indicating a portion of a page image described by the PDL data for which the conversion result has been reused. The reuse information output unit outputs reuse information indicating a portion of the page image for which the conversion result has been reused, by using the information stored in the reuse portion storage unit.

摘要： A print control apparatus includes a rendering unit, a sending unit, a distribution unit, and a saving unit. The rendering unit performs rendering in response to a print instruction described in a page-dependent page description language where details of a change of a print resource on a certain page are applied to other pages. The sending unit sends the entire print instruction including pages to the rendering unit. The distribution unit distributes, to the rendering unit, a process request specifying which of the pages is to be rendered. The saving unit saves a process state of the rendering unit after rendering a preset page. When executing rendering by extracting the print instruction of the page specified by the distributed process request to image data, if the process request is distributed in descending order, the rendering unit resumes the process state saved in the saving unit, and renders the specified page.

摘要： An image forming apparatus includes a processing unit group forming section, a converting section, and plural raster image processors. The processing unit group forming section forms plural processing unit groups by grouping plural processing units included in a print job. The converting section converts, for each of the plural processing units, the print job into intermediate data so as to form plural intermediate data groups corresponding to the plural processing unit groups. The plural raster image processors correspond to the plural intermediate data groups, each of the plural raster image processors performing a conversion process of converting a corresponding one of the plural intermediate data groups into raster data.

摘要： A print control apparatus includes rendering units performing rendering in response to a print instruction described in a page description language; a print instruction storage unit storing the print instruction for printing pages; a distribution unit sequentially distributing process requests, each specifying which page is to be rendered, and reference information for accessing the print instruction, to the rendering units; and a process request storage unit storing process requests. The rendering units each execute rendering by accessing the print instruction based on the reference information, and extracting a part of the print instruction of a specified page to image data. The distribution unit distributes a process request when there is a rendering unit to which the process request is distributable in ascending order, and, when there is no such rendering unit, stores the process request, and selects and distributes a smallest-page-number process request to one rendering unit.
