Claim 1:
2. The method of claim 1, wherein:
the second print module includes a plurality of syringe holders rotated by a rotary shaft so that a selected syringe holder among the plurality of syringe holders is rotated to the printing position, wherein a plurality of syringes are each installed in one of the plurality of syringe holders; and
when the Z value of the nozzle end of the syringe is measured in the nozzle end aligning operation (S100), each of the plurality of syringes is moved to the printing position one by one, and the Z value of the nozzle end of each syringe is measured,
the syringe whose Z value of the nozzle end is measured first is defined as a first syringe, and
the rotary shaft repeats forward rotation and reverse rotation within a rotation angle of 180° in each of clockwise and counterclockwise directions to move the selected syringe holder to the printing position so as to measure the Z value of the nozzle end of each syringe.
