Information processing unit, printing control unit, and control method thereof, and storage medium, and control program thereof

A printing control unit which executes printing-processing of a printing job in a case of mixed paper sizes, comprising:

• a plurality of paper feeding means which feed paper in the longitudinal or lateral direction, respectively, for specific paper sizes;
• and
• paper feeding means selecting means deciding from which of said plurality of paper feeding means the paper is to be fed, as to the paper sizes placeable in the longitudinal or lateral direction, on the basis of the standard paper information added to the job attributes of the printing job in the case of mixed paper sizes;
• wherein, when processing a page of a paper size placeable in the longitudinal or lateral direction upon printing-processing the printing job in the case of mixed paper sizes, the paper is fed from the paper feeding means selected by said paper feeding means selecting means, and the paper is not fed from the paper feeding means of a different paper direction.

A printing control unit executing printing processing of a printing job for mixed paper sizes, comprising:

• a plurality of paper feeding means which feed paper in the longitudinal or lateral direction, respectively, as to specific paper sizes;
• determining means which determines, when receiving a printing job for a plurality of paper sizes in mixture and printing-processing the same, whether or not there is available information showing that the received job is a mixed-paper job in the job attributes;
• acquiring means which acquires standard paper information added to the job attributes when it is determined by said determining means that there is available a piece of information indicating the presence of a mixed-paper job in said job attributes;
• paper size recognizing means which recognizes paper sizes mixed in said printing job through analysis of the printing job when it is determined by said determining means that there is unavailable a piece of information indicating the presence of a mixed-paper job in said job attributes;
• and
• paper feeding means selecting means which decides from which of said plurality of paper feeding means the paper is to be fed, as to the paper size placeable in the longitudinal or lateral direction, on the basis of the standard paper information acquired by said acquiring means or the paper sizes recognized by said paper size recognizing means.

A printing control method, which executes printing processing of a printing job comprising paper sizes in mixture, in a printing control unit having a plurality of paper feeding means feeding the paper in the longitudinal or lateral direction, as to specific paper sizes, comprising:

• a determining step, of determining, when receiving a printing job for a plurality of paper sizes in mixture and printing-processing the same, whether or not there is available information showing that the received job is a mixed-paper job in the job attributes;
• an acquiring step of acquiring standard paper information added to the job attributes when it is determined in said determining step that there is available a piece of information indicating the presence of a mixed-paper job in said job attributes;
• a paper size recognizing step, of recognizing paper sizes mixed in said printing job through analysis of the printing job when it is determined in said determining step that there is unavailable a piece of information indicating the presence of a mixed-paper job in said job attributes;
• and
• a paper feeding means selecting step, of deciding from which of said plurality of paper feeding means the paper is to be fed, as to the paper size placeable in the longitudinal or lateral direction, on the basis of the standard paper information acquired by said acquiring means or the paper sizes recognized in said paper size recognizing step.
