Abstract

A printing apparatus, having a conveyer, a first conveyer path, a printer, a cutter assembly, and a controller, is provided. The controller controls the printer to print images for at least two pages on a first side of a printing medium; after printing the images on the first side of the printing medium, controls the conveyer to move the printing medium to a second conveyer path being a different path from the first conveyer path through a switchback action and invert the printing medium by conveying in a second conveying direction; after inverting the printing medium, controls the printer to print an image in a predetermined part on a second side opposite to the first side of the printing medium; and after printing the image in the predetermined part on the second side of the printing medium, control the cutter assembly to cut the printing medium.

First claim

What is claimed is:

1. A printing apparatus, comprising:
a conveyer configured to convey a printing medium;
a first conveyer path, in which the printing medium is conveyed in a first conveying direction;
a printer arranged in the first conveyer path, the printer being configured to print images on the printing medium;
a cutter assembly arranged in the first conveyer path, the cutter assembly being configured to cut the printing medium; and
a controller configured to:
control the printer to print images for at least two pages on a first side being one of two sides of the printing medium,
after printing the images on the first side of the printing medium, control the conveyer to move the printing medium from the first conveyer path to a second conveyer path through a switchback action, the second conveyer path being a path branched from and connected to the first conveyer path, and invert the printing medium by conveying in a second conveying direction,
after inverting the printing medium, control the printer to print an image in a predetermined part on a second side opposite to the first side of the printing medium, the predetermined part being a frontward part of the printing medium in the first conveying direction,
after printing the image in the predetermined part on the second side of the printing medium, control the cutter assembly to cut the printing medium, and
after cutting the printing medium, control the printer to resume printing the image in a rearward part on the second side of the printing medium in the first conveying direction.

2. The printing apparatus according to claim 1 ,
wherein the cutter assembly is configured to cut the printing medium into a first part located frontward and a second part located rearward in the first conveying direction,
wherein the controller is configured to:
for printing the images on the first side of the printing medium, control the printer to print a first image in a range included in the first part on the first side of the printing medium and, before printing a second image, the second image being an image to appear on a page arranged to be later than a page containing the first image and earlier than a page containing a third image, print the third image in a range included in the second part on the first side of the printing medium, and
after inverting the printing medium, for printing the image in the predetermined part on the second side of the printing medium, control the printer to print the second image in a range included in the first part on the second side of the printing medium.

3. The printing apparatus according to claim 1 ,
wherein the cutter assembly is configured to cut the printing medium into a first part located frontward and a second part located rearward in the first conveying direction,
wherein, for printing the images on the first side of the printing medium and for printing the image in the predetermined part on the second side of the printing medium based on print data designated by a print job for creating a plurality of copies, each of the plurality of copies including a first image and a second image, the second image being an image to appear on a page arranged to be later than a page containing the first image in each of the plurality of copies, the controller is configured to:
control the printer to print the first image for a first copy being one of the plurality of copies in a range included in the first part on the first side of the printing medium and the first image for a second copy being another one of the plurality of copies in a range included in the second part on the first side of the printing medium, and
control the printer to print the second image for the first copy in a range included in the first part on the second side of the printing medium and the second image for the second copy in a range included in the second part on the second side of the printing medium.

4. A printing apparatus,
a conveyer configured to convey a printing medium;
a first conveyer path, in which the printing medium is conveyed in a first conveying direction;
a printer arranged in the first conveyer path, the printer being configured to print images on the printing medium;
a cutter assembly arranged in the first conveyer path, the cutter assembly being configured to cut the printing medium; and
a controller configured to:
control the printer to print images for at least two pages on a first side being one of two sides of the printing medium,
after printing the images on the first side of the printing medium, control the conveyer to move the printing medium from the first conveyer path to a second conveyer path through a switchback action, the second conveyer path being a path branched from and connected to the first conveyer path, and invert the printing medium by conveying in a second conveying direction,
after inverting the printing medium, control the printer to print an image in an entire printable range on a second side of the printing medium, and
after printing the image in the entire printable range on the second side of the printing medium, control the conveyer to convey the printing medium reversely in a third conveying direction opposite to the first conveying direction by a predetermined conveying amount, and

after conveying the printing medium in the third conveying direction by the predetermined conveying amount, control the cutter assembly to cut the printing medium.
