Abstract:
1. A print image processing system comprising: a plurality of logical page interpretation units that interpret assigned logical pages to be processed in input print data in parallel to obtain interpretation results; a dual interpretation unit that interprets an assigned logical page to be processed in the print data or interprets an element to be cached which is included in the logical page to obtain an interpretation result; a cache memory that stores interpretation results of elements to be cached; an assignment unit that assigns a logical page to be processed to each of the plurality of logical page interpretation units and assigns a logical page to be processed to the dual interpretation unit; and a print image data generation unit that generates print image data for the logical pages to be processed, using the interpretation results of the logical pages output from the logical page interpretation units or the interpretation result of the logical page output from the dual interpretation unit and using the interpretation results of the elements to be cached stored in the cache memory, the print image data generation unit supplying the generated print image data to a printer, each of the plurality of logical page interpretation units having a first page processing mode and a second page processing mode, the dual interpretation unit having the first page processing mode and a cache mode, the plurality of logical page interpretation units and the dual interpretation unit operating in the first page processing mode in a case where the amount of progress of interpretation of the print data is less than or equal to a predetermined threshold value, the plurality of logical page interpretation units operating in the second page processing mode and the dual interpretation unit operating in the cache mode in a case where the amount of progress of interpretation of the print data is greater than the threshold value.
