Image forming apparatus for converting print data into intermediate data, method for controlling image forming apparatus, and storage medium

A method for processing print data of a plurality of pages including a page being subjected to a predetermined command instructing an image forming apparatus not to output data for a page being subject to the predetermined command, the method comprising:

• generating, by a plurality of interpreters, intermediate data of the plurality of pages;
• according to completion of generation of intermediate data of a page by a corresponding interpreter, specifying a page subject to generation of intermediate data to notify the corresponding interpreter of the specified page;
• and
• generating image data of the respective pages from the generated intermediate data,
• wherein the generation of the intermediate data includes, based on the interpretation for the page being subjected to the predetermined command, any one interpreter of the plurality of interpreters generates the intermediate data of pages subsequent to the page being subjected to the predetermined command, and the rest of the plurality of interpreters does not generate the intermediate data of the pages subsequent to the page being subjected to the predetermined command.

An image forming apparatus configured to process print data of a plurality of pages, the image forming apparatus comprising:

• one or more controllers, having at least one processor that executes a program or having at least one application specific integrated circuit, configured to function as:
• a plurality of interpreters configured to generate intermediate data of the plurality of pages by interpreting the print data;
• and
• a control component configured to specify different pages for different interpreters, and, for each specified page, cause a corresponding interpreter to generate the intermediate data of the specified page;
• wherein a raster image of each specified page based on the generated intermediate data is generated, and
• wherein, based on the interpretation for an invalid page, the intermediate data of all pages subsequent to the invalid page is generated not according to the processing of the plurality of interpreters specified by the control component but by one of a specific interpreter from among the plurality of interpreters.
