Image forming apparatus having managing apparatus which creates print groups according to speed and associates print groups to a continuous paper strip

1. A managing apparatus comprising:

a processor configured to

use a plurality of continuous paper strips as recording media and receive a plurality of print jobs having different print speeds;

create print groups into which the plurality of print jobs are classified according to print speed;

acquire a remaining length of each of the plurality of continuous paper strips on which images are not yet formed and an image length which is a length of a continuous paper strip on which images are expected to be formed by performing the print jobs constituting each of the print groups;

compare the remaining length of each of the plurality of continuous paper strips to the image length of each of the print groups; and

associate each of the print groups with a corresponding one of the continuous paper strips so that all the print jobs constituting each of the print groups are performed on the corresponding one of the plurality of continuous paper strips.

2. The managing apparatus according to claim 1 , wherein the processor is configured to divide the print group into a plurality of new print groups in the case where the image length is longer than the remaining length.

3. The managing apparatus according to claim 1 , wherein the processor is configured to determine an order of performing the print jobs so that a dot density of an image formed on one of the plurality of continuous paper strips by a print job performed first of the print jobs constituting one of the print groups is higher than a dot density of an image formed on the one of the plurality of continuous paper strips by a print job performed last.

4. The managing apparatus according to claim 2 , wherein the processor is configured to determine an order of performing the print jobs so that a dot density of an image formed on one of the plurality of continuous paper strips by a print job performed first of the print jobs constituting one of the print groups is higher than a dot density of an image formed on the one of the plurality of continuous paper strips by a print job performed last.

5. The managing apparatus according to claim 3 , wherein the processor is configured to determine an order of performing the print jobs so that a dot density of an image formed on the one of the plurality of continuous paper strips gradually decreases from a dot density of an image formed by a print job performed first of the print jobs constituting one of the print groups to a dot density of an image formed by a print job performed last.

6. The managing apparatus according to claim 4 , wherein the processor is configured to determine an order of performing the print jobs so that a dot density of an image formed on the one of the plurality of continuous paper strips gradually decreases from a dot density of an image formed by a print job performed first of the print jobs constituting one of the print groups to a dot density of an image formed by a print job performed last.

7. A managing apparatus comprising:

a processor configured to

use a plurality of continuous paper strips as recording media and receive a plurality of print jobs having different print speeds;

create print groups into which the plurality of print jobs are classified according to print speed; and

determine an order of performing the print jobs so that a dot density of an image formed on one of the plurality of continuous paper strips by a print job performed first of the print jobs constituting one of the print groups is higher than a dot density of an image formed on the one of the continuous paper strips by a print job performed last of the print jobs constituting the one of the print groups.

8. A non-transitory computer readable medium storing a program causing a computer to execute a process for management, the process comprising:

using plurality of continuous paper strips as recording media and receiving a plurality of print jobs having different print speeds;

creating print groups into which the plurality of print jobs are classified according to print speed;

acquiring a remaining length of each of the plurality of continuous paper strips on which images are not yet formed and an image length which is a length of a continuous paper strip on which images are expected to be formed by performing the print jobs constituting each of the print groups;

comparing the remaining length of each of the plurality of continuous paper strips to the image length of each of the print groups; and

associating each of the print groups with a corresponding one of the plurality of continuous paper strips so that all the print jobs constituting each of the print groups are performed on the corresponding one of the plurality of continuous paper strips.

9. An image forming unit comprising:

a managing apparatus including

a processor configured to

use a plurality of continuous paper strips as recording media and receive a plurality of print jobs having different print speeds,

create print groups into which the plurality of print jobs are classified according to print speed,

acquire a remaining length of each of the plurality of continuous paper strips on which images are not yet formed and an image length which is a length of a continuous paper strip on which images are expected to be formed by performing the print jobs constituting each of the print groups,

compare the remaining length of each of the plurality of continuous paper strips to the image length of each of the print groups, and

associate each of the print groups with a corresponding one of the plurality of continuous paper strips so that all the print jobs constituting each of the print groups are performed on the corresponding one of the plurality of continuous paper strips, and

an image formation apparatus that performs on the plurality of continuous paper strips the plurality of print jobs constituting the print groups created by the managing apparatus and that forms images.
