Image forming apparatus, control method thereof, and storage medium

A method of controlling an image forming apparatus having a reading unit configured to execute reading processing for reading an image on an original document and execute printing processing for printing an image on a printing material, comprising:

• determining, when execution of the reading processing is instructed by a user while the print processing is being executed, whether or not the printing processing which is being executed uses a conveyance path which is to be used for the reading processing;
• setting, in accordance with an instruction from a user, which of the reading processing and the printing processing is preferentially executed;
• and
• if it is determined in the determining that the printing processing which is being executed does not use the conveyance path, control the reading unit to execute the reading processing before completion of the printing processing which is being executed, and if it is determined in the determining that the printing processing which is being executed uses the conveyance path and it is set in the setting to prioritize the printing processing, control the reading unit to execute the reading processing after completion of the printing processing which is being executed.

A non-transitory computer-readable storage medium storing a computer program for causing a computer to execute steps of a method of controlling an image forming apparatus having a reading unit configured to execute reading processing for reading an image on an original document and a printing unit configured to execute printing processing for printing an image on a printing material, comprising:

• determining, when execution of the reading processing is instructed by a user while the print processing is being executed, whether or not the printing processing which is being executed uses a conveyance path which is to be used for the reading processing;
• setting, in accordance with an instruction from a user, which of the reading processing and the printing processing is preferentially executed;
• and
• if it is determined in the determining that the printing processing which is being executed does not use the conveyance path, control the reading unit to execute the reading processing before completion of the printing processing which is being executed, and if it is determined in the determining that the printing processing which is being executed uses the conveyance path and it is set in the setting to prioritize the printing processing, control the reading unit to execute the reading processing after completion of the printing processing which is being executed.
