Abstract

The roll printing device includes a hardware processor configured to, on receiving a succeeding job during printing of a preceding job on a roll of print media, use a printing area for printing copies of an object of the preceding job and the width of the print media, to determine a blank area or areas to be created on the print media, and judge whether to print the succeeding job together with the preceding job with copies of the object of the succeeding job being arranged in the blank area or areas. The hardware processor is further configured to, according to the judgment result, define the layout of the copies of the object of the succeeding job in the blank area or areas, and change image data currently used for printing, at a certain time during the printing of the preceding job.

First claim

What is claimed is:

1. A roll printing device for printing a job on a roll of print media, comprising:
a raster-image processor that creates image data for printing copies of an object contained in a job to be printed;
a hardware processor that:
in response to receiving a succeeding job during printing of a preceding job by using the image data created from the preceding job, executes a judgment process including:
using a printing area for copies of an object contained in the preceding job to be printed and a width of the print media, to determine a blank area or areas to be created on the print media, in which none of the copies of the object of the preceding job is printed, extending along one or both of edges of the print media facing each other in a width direction of the print media, and
using a width of each of the blank area or areas and a size of a printing area in the width direction for a copy of an object contained in the succeeding job, to make a judgment whether to print the succeeding job together with the preceding job with copies of the object of the succeeding job to be printed, being arranged in the blank area or areas, and

on judging to print the succeeding job together with the preceding job, defines a layout of the copies of the object of the succeeding job to be printed, in the blank area or areas, and according to the layout, changes image data currently used for printing, from the image data created from the preceding job to the image data created from the preceding job and the image data created from the succeeding job, at a certain time during the printing of the preceding job; and

a print engine that uses the image data for printing, to print copies of an object or objects in the image data for printing, on the print media.

2. The roll printing device of claim 1 , wherein in the judgment process, the hardware processor:
uses a length of a printing area for a copy of the object of the preceding job in a machine direction of the print media and a number of the copies of the object of the preceding job to be printed, to calculate a length of a unprinted part of a printing area for the preceding job,
uses a length of a printing area for a copy of the object of the succeeding job in the machine direction and a number of the copies of the object of the succeeding job to be printed, to calculate a length of a printing area for the succeeding job, and
further makes the judgment by using a result of comparison between the length of the unprinted part of the printing area for the preceding job and the length of the printing area for the succeeding job.

3. The roll printing device of claim 2 , wherein on making a judgment that the length of the unprinted part of the printing area for the preceding job is not less than the length of the printing area for the succeeding job, the hardware processor:
defines the layout of the copies of the object of the succeeding job to be printed, in the blank area or areas so as to line up an end of the unprinted part of the printing area for the preceding job and an end of the printing area for the succeeding job, and
according to the layout, changes the image data currently used for printing, from the image data created from the preceding job to the image data created from the preceding job and the image data created from the successively job, at a time when a length of a current unprinted part of the printing area for the preceding job agrees with the length of the printing area for the succeeding job, during the printing of the preceding job.

4. The roll printing device of claim 2 , wherein on making a judgment that the length of the unprinted part of the printing area for the preceding job is less than the length of the printing area for the succeeding job, the hardware processor:
changes the image data currently used for printing, from the image data created from the preceding job to the image data created from the preceding job and the image data created from the successively job, at a first time during the printing of the preceding job, and then
changes the image data currently used for printing, from the image data created from the preceding job and the image data created from the successively job to the image data created from the succeeding job, at a second time when the printing of the preceding job is finished.

5. The roll printing device of claim 4 , wherein the hardware processor instructs the print engine to suspend printing at the second time.

6. The roll printing device of claim 4 , wherein on judging that a time period necessary to finish the printing of the succeeding job after the second time is shorter than a predetermined time period, the hardware processor instructs the print engine to stop printing after the printing of the succeeding job is finished.

7. The roll printing device of claim 1 , wherein in response to receiving a plurality of succeeding jobs during the printing of the preceding job, the hardware processor:
in the judging process, chooses, from the plurality of succeeding jobs, one or more jobs to be printed together with the preceding job with copies of the object contained in each of the one or more jobs to be printed, being arranged in the blank area or areas, and
in defining the layout, defines a layout of the copies of the object of each of the one or more jobs to be printed, in the blank area or areas.

8. The roll printing device of claim 1 , wherein the roll printing device is communicably connected with a second roll printing device, and wherein the hardware processor of the roll printing device, in response to receiving a succeeding job during printing of a preceding job by using the image data created from the preceding job, executes a judgment process including:
using the printing area for the copies of the object of the preceding job currently processed by the roll printing device and the width of the print media loaded on the roll printing device, to determine the blank area or areas to be created on the print media loaded on the roll printing device,
obtaining, from the second roll printing device, information of a blank area or areas to be created on the print media loaded on the second roll printing device, determined on a basis of a printing area for copies of an object contained in the preceding job currently processed by the second roll printing device and a width of the print media loaded on the second roll printing device,
comparing a width of each of the blank area or areas to be created on the printed area loaded on the roll printing device and each of the blank area or areas to be created on the printed area loaded on the second roll printing device, with the size of the printing area for a copy of the object contained in the succeeding job in the width direction, to choose one of the roll printing device and the second roll printing device to be used for printing the succeeding job together with the preceding job currently processed with the copies of the object of the succeeding job to be printed, being arranged in the blank area or areas to be created on the printed area loaded on the one of the roll printing device and the second roll printing device, and
instructing the hardware processor of the one of the roll printing device and the second roll printing device, to define a layout of the copies of the object of the succeeding job to be printed, in the blank area or areas, and according to the layout, change the image data currently used for printing, at a certain time during the printing of the preceding job currently processed by the one of the roll printing device and the second roll printing device.
