A head unit comprising:
- a base extended in a first direction;
- a first head fixed to the base, the first head comprising a nozzle array extended in the first direction;
- a second head fixed to the base, the second head comprising a nozzle array extended in the first direction, the second head configured to print continual dots with the first head;
- a first corrector configured to rotate and adjust an angle of the first head with respect to the base, the first corrector disposed at a first side in a second direction orthogonal to the first direction with respect to the first head;
- and
- a second corrector configured to rotate and adjust an angle of the second head with respect to the base, the second corrector disposed at a second side opposite to the first side in the second direction with respect to the second head, wherein
- the first head is configured to print first dots with a dot pitch in the first direction,
- the second head is configured to print second dots with the dot pitch in the first direction,
