Abstract

A printing device includes: a set unit on which a print medium can be set; a projection unit (projector) capable of projecting a first image onto the print medium set on the set unit; a printing unit capable of printing a second image on the print medium set on the set unit; and a control unit configured to modify a printing specification of the second image to be formed on the print medium based on modification information regarding a modification made to a projection specification of the first image projected onto the print medium by the projection unit.

First claim

What is claimed is:

1. An ink jet-type printing device comprising:
a set unit on which a print medium can be set;
a projection unit capable of projecting a first image onto the print medium set on the set unit, wherein projection of the first image onto the print medium by the projection unit does not cause permanent recording of the first image on the print medium;
an ejection head capable of printing a second image on the print medium set on the set unit by ejecting ink; and
a control unit configured to modify a printing specification of the second image to be formed on the print medium based on modification information regarding a modification made to a projection specification of the first image projected onto the print medium by the projection unit,
wherein the projecting unit is disposed on an exterior surface of a housing of the printing device and projects onto the print medium when the set unit is outside of the housing and the printing unit is disposed inside the housing and prints the second image when the set unit is inside the housing.

2. The ink jet-type printing device according to claim 1 , wherein
the control unit modifies a position of the second image to be formed on the print medium based on modification information regarding a modification made to a position of the first image projected onto the print medium by the projection unit.

3. The ink jet-type printing device according to claim 1 , wherein
the control unit modifies a size of the second image to be formed on the print medium based on modification information regarding a modification made to a size of the first image projected onto the print medium by the projection unit.

4. The ink jet-type printing device according to claim 1 , wherein
the control unit modifies an inclination of the second image to be formed on the print medium based on modification information regarding a modification made to an inclination of the first image projected onto the print medium by the projection unit.

5. The ink jet-type printing device according to claim 1 , wherein
the control unit modifies a color of the second image to be formed on the print medium based on modification information regarding a modification made to a color of the first image projected onto the print medium by the projection unit.

6. The ink jet-type printing device according to claim 1 , wherein
a range in which the projection specification is modified or a range in which the printing specification is modified is limited depending on a size of the set unit.

7. The ink jet-type printing device according to claim 1 , wherein
a focal length for projecting the first image onto the print medium by the projection unit is modified based on modification information regarding a modification made to a size of a gap between the set unit and the ejection head when the second image is to be printed on the print medium set on the set unit.

8. The ink jet-type printing device according to claim 1 , wherein the first image is identical to the second image.

9. The ink jet-type printing device according to claim 1 , wherein the first image is a guide image that visually indicates a position where the second image will be printed when the print medium is set on the set unit.

10. The ink jet-type printing device according to claim 1 , wherein the first image is a guide image for guiding an area in which the second image is to be printed on the print medium.

11. An ink jet-type printing device including a projection unit, an ejection head, a processor, and a non-transitory memory storing executable instructions, that when executed by the processor, cause the printing device to perform the following method, the method comprising:
projecting by the projection unit a first image onto a print medium set on a set unit of the printing device, wherein projection of the first image onto the print medium does not cause permanent recording of the first image on the print medium, wherein the projection unit is disposed on an exterior surface of a housing of the printing device and projects onto the print medium when the set unit is outside of the housing;
making a modification to a projection specification of the first image projected onto the print medium;
making a modification to a printing specification of a second image to be formed on the print medium based on modification information regarding the modification made to the projection specification; and
printing the second image on the print medium set on the set unit by ejecting ink from the ejection head.

12. The printing method as recited in claim 11 , further comprising printing the second image on the print medium according to the modified printing specification.
