A control system for controlling execution of calibration on a printing apparatus, comprising: acquiring means configured to acquire, from a printing apparatus to be controlled, and in response to a monitoring timing interval of the control system being reached: information of a first sheet type as a common calibration sheet type which is a sheet type that was used when a most recent common calibration was executed by the printing apparatus to be controlled, a result of said common calibration executed using the common calibration sheet type being applied to other sheet types; and information of a calibration state that is specified in accordance with a print volume used by the printing apparatus to be controlled; first determination means configured to determine, based on the acquired information of the first sheet type and the acquired information of the calibration state, whether the calibration state of the printing apparatus to be controlled for the first sheet type satisfies a predetermined condition; second determination means configured to determine whether a sheet of the first sheet type is fed to the printing apparatus to be controlled, wherein in a case in which the second determination means determines that the sheet of the first type is not fed the second determination means is configured to continuously determine whether the sheet of the first type is fed to the printing apparatus at predetermined intervals until a set predetermined period of time elapses; and control means configured to output an instruction for causing the printing apparatus to be controlled to execute common calibration including printing a predetermined patch, wherein the control means outputs the instruction for causing the printing apparatus to be controlled to execute calibration including printing the predetermined patch on the sheet of the first sheet type if the first determination means determines that the calibration state satisfies the predetermined condition and the second determination means determines that the sheet of the first sheet type is fed to the printing apparatus, and the control means does not output the instruction for causing the printing apparatus to execute the common calibration including printing the predetermined patch on the sheet of the first type if the first determination means determines that the calibration state does not satisfy the predetermined condition. acquiring means configured to acquire, from a printing apparatus to be controlled, and in response to a monitoring timing interval of the control system being reached: information of a first sheet type as a common calibration sheet type which is a sheet type that was used when a most recent common calibration was executed by the printing apparatus to be controlled, a result of said common calibration executed using the common calibration sheet type being applied to other sheet types;
