Changes in display that accompany the execution of the processing operation illustrated in FIGS. 3 and 4 will be described below.

FIG. 5 illustrates a specific example of four print jobs handled by the processor 31 (see FIG. 1). The four print jobs are given job names “print job #1” to “print job #4”.

The print job #1 may be rasterized at a speed of 100 meters/minute. The length (hereinafter referred to also as a “paper travel distance”) of paper to be consumed through execution of the print job #1 is 600 meters.

The print job #2 may be rasterized at a speed of 60 meters/minute. The length of paper to be consumed through execution of the print job #2 is 240 meters.

The print job #3 may be rasterized at a speed of 150 meters/minute. The length of paper to be consumed through execution of the print job #3 is 900 meters.

The print job #4 may be rasterized at a speed of 40 meters/minute. The length of paper to be consumed through execution of the print job #4 is 200 meters.

FIG. 6 illustrates a state in which the first print job #1 has been read out from the list managed by the job information management section 311. The maximum transport speed of the image forming apparatus 10 (see FIG. 1) is determined as 80 meters/minute. In FIG. 6, the print start time is represented as 0 o'clock sharp (=00:00:00).
