Printing apparatus, control method, and storage medium

A printing apparatus comprising:

• a printing unit configured to discharge a plurality of types of liquids to a print medium;
• a platen arranged to face the printing unit and configured to support the print medium;
• and
• a control unit configured to control the printing unit,
• wherein the control unit executes discharge control to discharge a liquid to a predetermined region of the platen after a printing operation, and
• it is determined whether the discharge control is to be executed based on an amount of a plurality of types of liquids discharged to the predetermined region before completion of the printing operation.

A control method for a printing apparatus including a printing unit configured to discharge a plurality of types of liquids to a print medium and a platen arranged to face the printing unit and configured to support the print medium, the method comprising

• executing discharge control to discharge, to a liquid discharged to the platen in a printing operation, a liquid of a type different from the liquid discharged to the platen after the printing operation,
• wherein in the discharge control, a second type of liquid is discharged to a first type of liquid discharged to the platen in the printing operation, and a fourth type of liquid is discharged to a third type of liquid discharged to the platen in the printing operation,
• the second type of liquid is a liquid having a higher deposition suppression effect for a component of the first type of liquid than the fourth type of liquid, and
• the fourth type of liquid is a liquid having a higher deposition suppression effect for a component of the third type of liquid than the second type of liquid.

A non-transitory computer-readable storage medium storing a program that causes a computer to execute a control method for a printing apparatus including a printing unit configured to discharge a plurality of types of liquids to a print medium and a platen arranged to face the printing unit and configured to support the print medium, the control method comprising

• executing discharge control to discharge, to a liquid discharged to the platen in a printing operation, a liquid of a type different from the liquid discharged to the platen after the printing operation,
• wherein in the discharge control, a second type of liquid is discharged to a first type of liquid discharged to the platen in the printing operation, and a fourth type of liquid is discharged to a third type of liquid discharged to the platen in the printing operation,
• the second type of liquid is a liquid having a higher deposition suppression effect for a component of the first type of liquid than the fourth type of liquid, and
• the fourth type of liquid is a liquid having a higher deposition suppression effect for a component of the third type of liquid than the second type of liquid.
