1. An image forming system comprising:
an information processing apparatus, which serves as a digital front end of an image forming apparatus, configured to generate print data based on a print job to form an image on a recording medium and output the print data to the image forming apparatus, the information processing apparatus being configured to be operable in a plurality of power modes including a normal power mode in which the print data is able to output and a power saving mode in which power consumption is less than the normal power mode and in which the print data is not able to output;
the image forming apparatus comprising:
a storage unit configured to store the information about two or more print data output from the information processing apparatus; and
an image forming unit configured to form an image on the recording medium based on the print data stored in the storage unit,
wherein, in a state where the power mode of the information processing apparatus is the normal power mode, in a case where a processing time required for completing an image forming based on the print data which has been received by the image forming apparatus from the information processing apparatus and has not been printed becomes more than a first predetermined value, outputting of the print data which has been received by the information processing apparatus and has not been transmitted to the image forming apparatus, from the information processing apparatus to the image forming apparatus, is stopped, and the power mode is transitioned from the normal power mode to the power saving mode,
wherein, in a state where the power mode of the information processing apparatus is the power saving mode, in a case where the processing time becomes less than a second predetermined value, the power mode is transitioned from the power saving mode to the normal power mode, and the outputting of the print data which has been received by the information processing apparatus and has not been transmitted to the image forming apparatus, from the information processing apparatus to the image forming apparatus, is started, and
wherein the second predetermined value is less than the first predetermined value.
