Embodiment Construction

[0021] A print data processing system according to an exemplary embodiment will be described below with reference to the drawings.

[0022] figure 1 An example of the print data processing system according to this exemplary embodiment is shown. The system includes a job controller 10 , a plurality of intermediate data generation units 20 , a rendering processor 30 , and a print engine 40 .

[0023] The job controller 10 manages print instructions input thereto as jobs, and executes the jobs by controlling other elements of the system. The input print instruction includes print data which is a document image to be printed and described in a page description language (PDL). A "job" is a print instruction given from a user, and is defined as a "job" on the system side. The job controller 10 analyzes the print data and instruction parameters (such as the number of copies and imposition settings) contained in the print instruction, generates management information for the job ac...

Abstract

The present invention discloses a print data processing system and a print data processing method. The print data processing system includes plural intermediate data generation units, an allocation unit, one or more memories, a print image conversion unit, and a reprint controller. Each intermediate data generation unit interprets PDL data and generates intermediate data in units of pages. The allocation unit allocates processes of interpreting the PDL data to the intermediate data generation units in units of pages and causes the intermediate data generation units to execute processes of interpreting pages in parallel. The one or more memories store pieces of intermediate data of the individual pages. The print image conversion unit acquires the pieces of intermediate data, converts the acquired data to print image data, and supplies the print image data to a printer. The reprint controller performs control to cause the print image conversion unit to reacquire the pieces of intermediate data and to reconvert the reacquired data to the print image data.

Description

technical field [0001] The invention relates to a print data processing system and a print data processing method. Background technique [0002] Various techniques are available that utilize multiple raster image processors (RIPs) to process print data in parallel to increase print output speed. Here, RIP is hardware or software for converting print data described in a page description language (PDL) such as PostScript (registered trademark) or Portable Document Format (PDF) into a printable or displayable raster format, etc. data. [0003] For example, Japanese Unexamined Patent Application Publication No. 2011-201146 discloses a system that performs parallel processing using a plurality of external RIP devices to increase the speed of RIP processing. In this system, in the case where there is an unused external RIP device while RIP processing is being performed on the current job, the job management unit requests the preprocessor to perform advance processing on the subs...
