1. A printing apparatus comprising:
a head including a plurality of nozzles configured to discharge an ink having photo-curing property to a printing medium;
an irradiator including a plurality of light source rows configured to irradiate the ink on the printing medium with a light;
a carriage configured to move the head and the irradiator in a first direction; and
a controller, wherein:
each of the plurality of light source rows is constructed by a plurality of light sources aligned in a second direction crossing the first direction;
the plurality of light source rows is arranged in the first direction;
the controller is configured to:
execute a first obtaining operation of obtaining a gap between the irradiator and the printing medium;
execute a discharging operation of discharging the ink from the head to the printing medium;
execute an irradiating operation of irradiating the ink on the printing medium with the light from the irradiator; and
switch off a part of the plurality of light source rows in the irradiating operation in a case that the gap obtained in the first obtaining operation is a second gap; and
a number of the plurality of light sources switched on in the irradiating operation in a case that the gap obtained in the first obtaining operation is a first gap is greater than a number of the plurality of light sources switched on in the irradiating operation in the case that the gap obtained in the first obtaining operation is the second gap smaller than the first gap.
