In the case of the rolled paper #22, meanwhile, the print speed of the print job #26, among the allocated print jobs, is the lowest. Therefore, the print speed for the rolled paper #22 is determined as 40 meters/minute. In this case, it takes 4 hours and 10 minutes to print the print jobs #21, #22, and #26 allocated to the rolled paper #22.

Therefore, it takes 5 hours 56 minutes 15 seconds to print the print jobs #21 to #26, excluding the paper replacement time.

While exemplary embodiments of the present disclosure have been described above, the technical scope of the present disclosure is not limited to the exemplary embodiments discussed earlier. It is apparent from the following claims that a variety of modifications and improvements that may be made to the exemplary embodiments discussed earlier also fall within the technical scope of the present disclosure.

In the exemplary embodiments discussed earlier, the management server 30 (see FIG. 1) executes the determination of allocation of the print jobs to the rolled paper and the update of an estimation of the time needed to execute printing according to the combination of the allocated print jobs. However, such functions may be executed by the image forming apparatus 10 alone, or the management server 30 and the image forming apparatus 10 may cooperate with each other to execute the determination of allocation of the print jobs to the rolled paper and the update of an estimation of the time needed to execute printing according to the combination of the allocated print jobs.
