Printing apparatus, control method, and storage medium

A control method for a printing apparatus including:

• a printing head which includes a plurality of first heating resistance elements which generate an energy for ejecting a liquid from a plurality of ejection ports, and a plurality of second heating resistance elements which generate an energy for generating a flow of the liquid in a flow passage;
• and
• a control unit which controls the printing head based on ejection data indicating ejection or non-ejection for each of the plurality of ejection ports, and drive data indicating whether or not driving is enabled for the plurality of second heating resistance elements, the control unit including a heat-level calculation unit which derives a heat level based on the ejection data and the drive data, and a drive pulse generation unit which generates a drive pulse in accordance with the derived heat level, in which in a case where the ejection data for each of the plurality of ejection ports indicates non-ejection and the drive data indicates that driving is enabled, the control unit drives the second heating resistance element corresponding to the each ejection port,
• the control method comprising:
• calculating the number of the second heating resistance elements to be simultaneously driven, based on the ejection data and the drive data by means of the heat-level calculation unit.

A non-transitory computer readable storage medium storing a program which causes a computer to execute a control method for a printing apparatus including:

• a printing head which includes a plurality of first heating resistance elements which generate an energy for ejecting a liquid from a plurality of ejection ports, and a plurality of second heating resistance elements which generate an energy for generating a flow of the liquid in a flow passage;
• and
• a control Unit which controls the printing head based on ejection data indicating ejection or non-ejection for each of the plurality of ejection ports, and drive data indicating whether or not driving is enabled for the plurality of second heating resistance elements, the control unit including a heat-level calculation Unit which derives a heat level based on the ejection data and the drive data, and a drive pulse generation unit which generates a drive pulse in accordance with the derived heat level, in which in a case where the ejection data for each of the plurality of ejection ports indicates non-ejection and the drive data indicates that driving is enabled, the control Unit drives the second heating resistance element corresponding to the each ejection port,
