A printing method comprising: performing printing on a recording medium, wherein, in the printing, a printing apparatus is used, which includes a head unit in which a plurality of heads discharging inks are disposed side by side, and discharges the inks while relatively moving the head unit and the recording medium, wherein the printing apparatus performs the printing while the head unit reciprocates with respect to the recording medium, and wherein, when the head unit is logically divided into at least three groups of a first group, a second group, and a third group in a direction (y) where the plurality of heads are positioned side by side, with the first group, the second group, and the third group arranged in a row in the direction in which the plurality of heads are positioned side by side, the first group and the second group share one head, the head being shared is set as a first reference head, the second group and the third group share one head, and the head being shared is set as a second reference head, in the printing, a first correction is performed in which a discharging position, where a first correction target head (132a-e) other than the first reference head among the heads of the first group discharges the inks, is corrected based on a first position where the first reference head discharges the inks, and a discharging position, where a second correction target head (132g-k) other than the first reference head among the heads of the second group discharges the inks, is corrected based on a second position, different from the first position, where the first reference head discharges the inks, and a second correction is performed in which a discharging position, where a third correction target head (132L-p) other than the second reference head among the heads of the third group discharges the inks, is corrected based on the second discharging position where the first reference head discharges the inks and the discharging position where the second reference head discharges the inks. performing printing on a recording medium, wherein, in the printing, a printing apparatus is used, which includes a head unit in which a plurality of heads discharging inks are disposed side by side, and discharges the inks while relatively moving the head unit and the recording medium, wherein the printing apparatus performs the printing while the head unit reciprocates with respect to the recording medium, and wherein, when the head unit is logically divided into at least three groups of a first group, a second group, and a third group in a direction (y) where the plurality of heads are positioned side by side, with the first group, the second group, and the third group arranged in a row in the direction in which the plurality of heads are positioned side by side, the first group and the second group share one head, the head being shared is set as a first reference head, the second group and the third group share one head, and the head being shared is set as a second reference head, in the printing, a first correction is performed in which a discharging position, where a first correction target head (132a-e) other than the first reference head among the heads of the first group discharges the inks, is corrected based on a first position where the first reference head discharges the inks, and a discharging position, where a second correction target head (132g-k) other than the first reference head among the heads of the second group discharges the inks, is corrected based on a second position, different from the first position, where the first reference head discharges the inks, and a second correction is performed in which a discharging position, where a third correction target head (132L-p) other than the second reference head among the heads of the third group discharges the inks, is corrected based on the second discharging position where the first reference head discharges the inks and the discharging position where the second reference head discharges the inks.
