The six print jobs #21 to #26 handled in FIG. 23 are the same as those in the case of the third exemplary embodiment. That is, the print jobs are the same as those indicated in FIG. 19. The length of one roll of rolled paper and the maximum transport speed of the image forming apparatus 10 (see FIG. 1) are also the same as those according to the third exemplary embodiment.

In the present exemplary embodiment, as illustrated in FIG. 22, one print job is selected in the descending order of the print speed, and added to the print list corresponding to the rolled paper.

Therefore, the print jobs #23, #25, and #24 are allocated to the rolled paper #21, and the print jobs #21, #22, and #26 are allocated to the rolled paper #22.

For example, in the case of the rolled paper #21, the print speed of the print job #24, among the allocated print jobs, is the lowest. Therefore, the print speed for the rolled paper #21 is determined as 80 meters/minute. A speed of 80 meters/minute is the same as the maximum transport speed of the image forming apparatus 10 (see FIG. 1).

In this case, it takes 1 hour 46 minutes 15 seconds to print the print jobs #23, #25, and #24 allocated to the rolled paper #21.
