Print image processing system and non-transitory computer readable medium

A non-transitory computer readable medium storing a program causing a computer to execute a process, the process comprising:

• operating a plurality of logical page interpretation units to interpret different logical pages in print data in parallel to obtain interpretation results and to output the interpretation results;
• operating a caching interpretation unit to interpret an element to be cached which is included in each of logical pages in the print data to obtain interpretation results and to store the interpretation results in a cache unit;
• generating print image data of the logical pages using the interpretation results of the logical pages output from the logical page interpretation units and the interpretation results of the elements to be cached stored in the cache unit;
• and
• supplying the generated print image data to a printer, wherein
• in response to detection of an element to be cached for which an interpretation result has not been stored in the cache memory, the caching interpretation unit interprets the detected element to be cached to obtain an interpretation result, and stores the interpretation result in the cache unit in association with cache identification information which is generated from data of the detected element to be cached in accordance with a predetermined generation rule,
• each of the plurality of logical page interpretation units generates, for an element to be cached which is included in a logical page to be processed, a cache reference command including cache identification information which is generated from data of the element to be cached in accordance with the generation rule without interpreting the element to be cached, and incorporates the generated cache reference command, as an interpretation result of the element to be cached, into the interpretation result of the logical page to be processed, and
• print image data is generated from the interpretation results of the logical pages output from the plurality of logical page interpretation units, by
• in response to detection of a cache reference command from the interpretation results of the logical pages,
• acquiring from the cache unit an interpretation result of an element to be cached corresponding to the cache identification information included in the cache reference command,
• generating print image data for the element to be cached corresponding to the cache identification information using the acquired interpretation result, and
• combining the generated print image data with the print image data for the logical pages.
