There is provided a printing apparatus includes a head having a slow-permeation-black-nozzle-group which discharges slow-permeation-black-ink, and an excessive-permeation-black-nozzle-group which are arranged at the same pitch as the slow-permeation-black-nozzle-group and are deviated from the slow-permeation-black-nozzle-group by ½ pitch in a sub scanning direction, and a control unit which controls scanning of the head in a main scanning direction and ink discharging through each group. In the printing apparatus, the control unit controls to perform printing in any one of a plurality of printing modes including a normal printing mode in which printing is performed such that slow-permeation-black-ink is discharged through the slow-permeation-black-nozzle-group while excessive-permeation-black-ink is not discharged through the excessive-permeation-black-nozzle-group, and a high-speed printing mode in which printing is performed such that slow-permeation-black-ink is discharged through the slow-permeation-black-nozzle-group and excessive-permeation-black-ink is discharged through the excessive-permeation-black-nozzle-group.
