An ink-jet printer using a small and a large line feeds has been disclosed. The ink-jet printer comprises a head on which B ink spraying nozzles are arranged at fixed nozzle intervals in the vertical scanning direction and a vertical scanning mechanism, wherein the nozzle interval is A times the dot pitch and the printing action is composed of a single printing scan in the main scanning direction, a small line feed printing that repeats an action (CxA-1) times, in which after a small line feed that relatively moves the recording medium in the vertical scanning direction by the amount of n times the nozzle interval plus one dot pitch ((Axn+1)xd) is performed, a single printing scan in the main scanning direction is performed, and a subsequent large line feed printing that performs a large line feed by the amount of (BxA-(Axn+1)(CxA-1))xd.
