Image forming system, method of controlling image forming system, and storage medium

A method of controlling an image forming system, the image forming system configured to perform case binding in which a bundle of printed sheets as a body is bound by being wrapped with a cover, the method comprising:

• receiving a number of sheets on which a test print pattern image is to be printed;
• receiving a print instruction to print the test print pattern image;
• and
• performing control to perform printing based on the print instruction,
• wherein, in a case where execution of predetermined postprocessing different from the case binding is set and the print instruction is received, the performing control is performed to print the pattern image on the received number of sheets, and in a case where execution of the case binding is set and the print instruction is received, the performing control is performed to print the pattern image on a number of sheets greater by a predetermined number of sheets than the received number of sheets.

A non-transitory computer-readable storage medium that stores a program for causing a computer to perform a method of controlling an image forming system, the image forming system configured to perform case binding in which a bundle of printed sheets as a body is bound by being wrapped with a cover, the method comprising:

• receiving a number of sheets on which a test print pattern image is to be printed;
• receiving a print instruction to print the test print pattern image;
• and
• performing control to perform printing based on the print instruction,
• wherein, in a case where execution of predetermined postprocessing different from the case binding is set and the print instruction is received, the control is performed to print the pattern image on the received number of sheets, and in a case where execution of the case binding is set and the print instruction is received, the control is performed to print the pattern image on a number of sheets greater by a predetermined number of sheets than the received number of sheets.
