Image forming apparatus

A printing apparatus to which a first enclosing unit in which recording media of a first size have been enclosed so as to be fed in a long edge direction and a second enclosing unit in which the recording media of said first size have been enclosed so as to be fed in a short edge direction can be attached, comprising:

• receiving means for receiving print information of a plurality of pages and size information showing that said print information has print information which is to be printed onto the recording medium of said first size and print information which is to be printed onto a recording medium of a size other than said first size from an external apparatus;
• and
• selecting means for selecting an enclosing unit for feeding the recording medium for printing the print information which is printed onto the recording medium of said first size on the basis of said received size information.

A printing apparatus which can attach an enclosing unit which can feed recording media of a first size in a long edge direction or a short edge direction, comprising:

• receiving means for receiving print information of a plurality of pages and size information showing that said print information has print information which is to be printed onto the recording medium of said first size and print information which is to be printed onto a recording medium of a size other than said first size from an external apparatus;
• and
• selecting means for selecting a feeding direction from said enclosing unit of the recording medium for printing the print information which is printed onto the recording medium of said first size on the basis of said received size information.

A paper feed control method which is executed by an image forming apparatus having a function for feeding mixed sheets of paper of a plurality of sizes and forming an image onto each paper, wherein

• in the case where a plurality of paper sizes exist mixedly in one image forming job, a paper feeding direction for performing a paper feed in the vertical direction or a paper feed in the lateral direction to the paper which can be fed in both of the vertical direction and the lateral direction is specified on the basis of set paper mixture information.

A printing method in a printing apparatus to which a first enclosing unit in which recording media of a first size have been enclosed so as to be fed in a long edge direction and a second enclosing unit in which the recording media of said first size have been enclosed so as to be fed in a short edge direction can be attached, comprising:

• a receiving step of receiving print information of a plurality of pages and size information showing that said print information has print information which is to be printed onto the recording medium of said first size and print information which is to be printed onto a recording medium of a size other than said first size from an external apparatus;
• and
• a selecting step of selecting an enclosing unit for feeding the recording medium for printing the print information which is printed onto the recording medium of said first size on the basis of said received size information.
