Claim Text:
1. An inkjet printer that has an inkjet head in which a plurality of nozzle rows that discharge ink are aligned in parallel, and performs printing on a sheet while switching resolution, by discharging ink from a nozzle row selected from the plurality of nozzle rows while the inkjet head and the sheet are relatively moved, the inkjet printer comprising: an influence calculator that calculates an influence indicating a degree of an influence of generation of a satellite on the sheet on the basis of a printing condition, before printing; and a controller that controls the inkjet head so that (i) one pixel row is formed by discharging the ink from at least two nozzle rows among the plurality of nozzle rows when the influence calculated by the influence calculator does not exceed a predetermined threshold value, and (ii) one pixel row is formed by discharging the ink from one nozzle row among the plurality of nozzle rows when the influence calculated by the influence calculator meets or exceeds the predetermined threshold value, wherein the controller controls discharging timing of the inkjet head so that the ink is discharged by each row in a decreasing order of elapsed time from a nozzle row with the longest elapsed time since ink was discharged therefrom for each pixel row on the sheet on which printing is to be performed, when the influence calculated by the influence calculator exceeds the predetermined threshold value.
