In the case of the second exemplary embodiment, print jobs to be allocated to rolls of rolled paper are determined in the order of registration in the job information management section 311 (see FIG. 2). Therefore, the print jobs #21 to #23, the total sum of the paper travel distances of which is 9500 meters, are allocated to rolled paper #21, and the print jobs #24 to #26, the total sum of the paper travel distances of which is 9000 meters, are allocated to rolled paper #22.

In the case of FIG. 20, the print speed, which is determined from the rasterizing speed, of the print job #22 is the lowest at 50 meters/minute, among those of the print jobs #21 to #23. Meanwhile, the print speed, which is determined from the rasterizing speed, of the print job #26 is the lowest at 40 meters/minute, among those of the print jobs #24 to #26. Therefore, the print speed corresponding to the rolled paper #21 is determined as 50 meters/minute, and the print speed corresponding to the rolled paper #22 is determined as 40 meters/minute.

As a result, it takes 3 hours and 10 minutes to print the print jobs #21 to #23 allocated to the rolled paper #21, and it takes 3 hours and 45 minutes to print the print jobs #24 to #26 allocated to the rolled paper #22.

Therefore, it takes 6 hours and 55 minutes to print the print jobs #21 to #26, excluding the paper replacement time.

FIG. 21 illustrates the result of applying the schedule determination method adopted in the third exemplary embodiment.
