Claim 8:
9. An ink discharge apparatus comprising:
a discharge head having a plurality of nozzle rows arragned in a first direction, each of the nozzle rows including a plurality of nozzles aligned in a second direction intersecting with the first direction; and
a controller,
wherein the controller is configured to execute;
a mode determining process to receive a print job and to determione whether a print mode is a low gap print mode or a high gap print mode based on the print job, the low gap print mode being a print mode where a distance between the nozzles and a discharge target medium is a low gap, the high gap print mode being a print mode where the distance between the nozzles and the discharge target medium is a high gap larger than the distance of the low gap; and
a number of discharge reducing process to reduce a total number of discharging ink per unit time from the nozzles as compared whit the case of the low gap print mode, if the priont mode is determioned as the high gap print mode,

wherein the discharge head is configured to move a number of times along the first direction,
if the print mode is determined as the high gap print mode, the controller is configured to reduce the total number of discharging ink droplets from the nozzles of the nozzle rows per one movement of the discharge head alont the first direction,
the print job inludes information idicating the low gap print mode, the high gap print mode, and a middle gap print mode where the distance between the nozzles and the discharge target medium is longer than the distance of the low gap and shorter than the distance of the high gap, and
the controller is configured to control the discharge head to execute printing such that as the distance between the nozles and the discharge target medium increases, a number of movement of the discharge head along the first direction increases.
