Abstract

A control method in a printing apparatus includes printing, by a printing unit, an adjustment image for adjusting a printing position on a sheet, conveying, by a conveying unit, the sheet on which the adjustment image is printed, reading, by a reading unit, an image to generate image data, the reading unit being executable to perform reading by a first reading method for reading an image of a sheet without conveying the sheet or a second reading method for reading the image of the sheet while conveying the sheet, and determining, based on that a type of the sheet on which the adjustment image is to be printed is a specific type, to read the adjustment image by the first reading method.

Claims

1. A printing apparatus comprising:

a printing unit configured to print an adjustment image for adjusting a printing position on a sheet;

a conveying unit configured to convey the sheet on which the adjustment image is printed;

a reading unit configured to read an image to generate image data, the reading unit being executable to perform reading using a first reading method for reading an image of a sheet without conveying the sheet or a second reading method for reading the image of the sheet while conveying the sheet;

a receiving unit configured to receive a first instruction for causing the reading unit to read the adjustment image using the first reading method or a second instruction for causing the reading unit to read the adjustment image using the second reading method;

a displaying unit configured to display on a screen a first button via which the receiving unit receives the first instruction from a user and a second button via which the receiving unit receives the second instruction from the user;

an obtaining unit configured to obtain, in a case where the first instruction is received from the user via the first button, an amount of shift in the printing position based on image data generated by reading, using the first reading method, the adjustment image printed on the sheet, and obtain, in a case where the second instruction is received from the user via the second button, the amount of shift in the printing position based on image data generated by reading, using the second reading method, the adjustment image printed on the sheet; and

a print controlling unit configured to control the printing unit based on the amount of shift in the printing position so that an image is printed on the sheet,

wherein the displaying unit displays, in a case where a type of the sheet on which the adjustment image is to be printed is a specific type, the first button without displaying the second button on the screen.
