Printing apparatus, print processing method, and program

A printing apparatus comprising:

• an input unit configured to input print data including a plurality of records each including a plurality of page data each containing either one or both of reusable data and variable data;
• an extracting unit configured to extract the reusable data every page data included in the record;
• an adding unit configured to, when the reusable data which has been extracted for the first time in the print data is included in the reusable data extracted by the extracting unit, add information to the page data including the reusable data;
• a forming unit configured to form a page image every page data included in the record;
• and
• a transfer unit configured to, in the case where the information has been added to the page data of the page image formed by the forming unit, hold the page images formed by the forming unit, and in the case where the information is not added to the page data of the page image formed by the forming unit, transfer the page image formed by the forming and the page images which have already been held to a printer engine.

A printing method carried out in a printing apparatus, the method comprising:

• inputting print data including a plurality of records each including a plurality of page data each containing either one or both of reusable data and variable data;
• extracting the reusable data every record;
• when the reusable data which has been extracted for the first time in the print data is included in the reusable data extracted in the extracting step, adding information to the record including the first-extracted reusable data;
• forming a page image every page data included in the record;
• in the case where the information has been added to the record, holding the page images which are formed in the forming step until the page images of all of the page data included in the record are formed in the forming step and transferring the held page images of all of the page data included in the record to a printer engine;
• and
• in the case where the information is not added to the record, each time the page image of the page data included in the record is formed in the forming step, transferring the formed page image to the printer engine.
