Abstract

Embodiments of the present disclosure are directed to a printing system comprising accepting a request to print based on a capture image of an image projected by the projection unit; determining whether or not printing based on the capture image of the image projected by the projection unit is possible; in a case where it is determined that the printing of the image projected by the projection unit is possible, permitting the printer to print based on the capture image of the image projected by the projection unit on the basis of the request accepted; and in a case where it is determined that the printing of the image projected by the projection unit is not possible, restricting the printer from printing based on the capture image of the image projected by the projection unit on the basis of the print request accepted.

First claim

What is claimed is:

1. A printing system comprising:
a projection unit that projects an image;
a printer;
an accepting unit that accepts a request to print based on a capture image of an image projected by the projection unit;
a determination unit that determines whether or not printing based on the capture image of the image projected by the projection unit is possible; and
a control unit that:
in a case where the determination unit determines that the printing of the image projected by the projection unit is possible, permits the printer to print based on the capture image of the image projected by the projection unit on the basis of the request accepted by the accepting unit, and
in a case where the determination unit determines that the printing of the image projected by the projection unit is not possible, restricts the printer from printing based on the capture image of the image projected by the projection unit on the basis of the print request accepted by the accepting unit.

2. The printing system according to claim 1 ,
wherein the image projected by the projection unit includes an image based on a file, and
in a case where the determination unit determines that the printing of the image projected by the projection unit is not possible, the control unit acquires the file.

3. The printing system according to claim 2 ,
wherein in a case where the determination unit determines that the printing of the image projected by the projection unit is not possible, the control unit acquires information for acquiring the file, and acquires the file on the basis of the information acquired.

4. The printing system according to claim 3 ,
wherein in a case where the determination unit determines that the printing of the image projected by the projection unit is not possible, the control unit further determines whether or not information for acquiring the file can be acquired, and
in a case where it is determined that the information can be acquired, the control unit acquires the information.

5. The printing system according to claim 2 ,
wherein the image projected by the projection unit includes an image based on a file, and
in a case where the determination unit determines that the printing of the image projected by the projection unit is not possible, the control unit acquires the file and causes the printer to print based on the file acquired.

6. The printing system according to claim 1 , further comprising:
a reader that reads a document,
wherein the projection unit is further capable of projecting an image read by the reader.

7. A method of controlling a printing system, the printing system including a projection unit that projects an image and a printer, the method comprising:
accepting a request to print based on a capture image of an image projected by the projection unit;
determining whether or not printing based on the capture image of the image projected by the projection unit is possible;
in a case where it is determined that the printing of the image projected by the projection unit is possible, permitting the printer to print based on the capture image of the image projected by the projection unit on the basis of the request accepted; and
in a case where it is determined that the printing of the image projected by the projection unit is not possible, restricting the printer from printing based on the capture image of the image projected by the projection unit on the basis of the print request accepted.

8. A non-transitory computer-readable storage medium storing a computer program for causing a computer to execute a method of controlling a printing system, the printing system including a projection unit that projects an image and a printer, the method comprising:
accepting a request to print based on a capture image of an image projected by the projection unit;
determining whether or not printing based on the capture image of the image projected by the projection unit is possible;
in a case where it is determined that the printing of the image projected by the projection unit is possible, permitting the printer to print based on the capture image of the image projected by the projection unit on the basis of the request accepted; and
in a case where it is determined that the printing of the image projected by the projection unit is not possible, restricting the printer from printing based on the capture image of the image projected by the projection unit on the basis of the print request accepted.
