Embodiment Construction

[0032] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] refer to figure 1 , described first is an example when performing 2-up processing in which two logical pages are arranged and printed on a single physical page. exist figure 1 In the example, logical page 1 and logical page 2 are arranged on physical page 1. In the illustration, it is assumed that the direction from left to right is the main scanning direction in which the printing operation is performed in the order of raster scanning by the printing engine. For example, in the case of a print engine of an electrophotographic system using a raster output scanner (ROS), the main scanning direction is the scanning direction of a laser beam of a rotating photoconductor. In the case of a print engine of an inkjet system, the main scanning direction is the scanning direction of the print head. The sub-scanning direction relative to the main scanni...

Abstract

An image data processing system, includes a plurality of first units that interpret data of assigned logical pages included in document data described in a page description language, generate intermediate data of the logical pages, divide the generated intermediate data of the logical pages into intermediate data on the basis of logical sections which are sections on the logical pages, and output the divided intermediate data; and a plurality of second units that correspond to physical sections which are sections on a physical page, generate print image data from intermediate data of a plurality of logical sections included in corresponding physical sections from among the intermediate data of the logical sections on the logical pages generated by the plurality of first units, and output the generated print image data to a printer.

Description

technical field [0001] The invention relates to an image data processing system. Background technique [0002] There is a known technique for increasing print output speed by processing print data in parallel by a plurality of raster image processors (RIPs). The RIP is a device that develops data described in a page description language (hereinafter referred to as PDL) such as PostScript (registered trademark) into print image data such as raster data or spaced data that a print engine can handle. The process of developing PDL data into print image data is sometimes called RIP process. [0003] Also, an imposition function is known that arranges a plurality of processing units (for example, pages) described with PDL data side by side on one side of a sheet or arranges the units in such a manner that they partially or completely overlap each other. An example of an imposition function is n-up. Here, n is a natural number of 2 or more. n-up is a process for printing n page...
