1. An inkjet printing apparatus comprising:
a print scanning unit configured to carry out a print scan on a print medium by causing a print head that ejects an ink in accordance with print data to scan in a main scanning direction;
a conveying unit configured to perform conveyance of the print medium in a direction crossing the main scanning direction;
a heating unit configured to heat the print head before carrying out each of the print scans; and
a controlling unit configured to control the print scanning unit, the conveying unit, and the heating unit,
wherein the first print scan in a first print job for a first type of print medium is carried out in a case where a temperature of the print head is higher than a first target temperature,
wherein each of the second and later print scans in the first print job is carried out in a case where a temperature of the print head is higher than a second target temperature,
wherein the first print scan in a second print job for a second type of print medium different from the first type of print medium is carried out in a case where a temperature of the print head is higher than the first target temperature, and
wherein each of the second and later print scans in the second print job is carried out in a case where a temperature of the print head is higher than a third target temperature different from the second target temperature.
