Abstract
A printing apparatus and a printing method that make it easy to visually confirm whether a printing defect has occurred are provided. A printing method according to an application example includes printing of image in which an image is printed onto a medium by a printing apparatus, detecting of state in which a state change is detected during operations of the printing apparatus in the printing of image, and printing of information in which state change information is printed onto the medium, based on the state change detected in the detecting of state. The state change information is associated with a position in the image where the state change is detected.
Claims20
A printing method comprising:
- printing an image onto a medium while scanning an ejection head in a scan direction, the ejection head being configured to eject liquid droplets onto the medium;
- detecting a state change for each scan during the printing of the image;
- and
- printing state change information corresponding to the state change onto the medium, responsive to detecting the state change, wherein
- the state change information is printed so as not to overlap with a printed area of the image;
- and
- the state change information is associated with a position in the image where the state change is detected.
A printing apparatus comprising:
- a printing unit configured to print an image onto a medium while scanning an ejection head in a scan direction, the ejection head being configured to eject liquid droplets onto the medium;
- a state detecting unit configured to detect a state change while the printing unit prints the image;
- and
- a controller configured to cause the printing unit to print state change information corresponding to the state change onto the medium, responsive to detecting the state change, such that the state change information is printed so as not to overlap with a printed area of the image,
- wherein the state change information is associated with a position in the image where the state change is detected.
