• displaying a print setting screen which is able to accept a change of print setting of the job based on the instruction being accepted on the screen,
• in a case where an amount printed according to the second printing mode would not exceed the second printable amount if print setting of the job is changed to print setting accepted in the print setting screen, executing the job in which print setting of the job is changed to print setting accepted in the print setting screen, and
• in a case where an amount printed on printing according to the second printing mode would exceed the second printable amount even if print setting of the job is changed to print setting accepted in the print setting screen, repeatably displaying the print setting screen until print setting of the job is set such that the amount to be printed on printing according to the second printing mode does not exceed the second printable amount.

A non-transitory computer-readable storage medium storing a program configured to cause a computer to function to:

• obtain a first printable amount corresponding to an upper limit on printing according to a first printing mode and a second printable amount corresponding to an upper limit on printing according to a second printing mode;
• in a case where an amount to be printed due to execution of a job designating printing according to the first printing mode exceeds the first printable amount, display a screen which is able to accept an instruction for changing printing according to the first printing mode designated by the job to printing according to the second printing mode;
