Abstract
There is provided a printer including first to fourth head chips, and first and second rollers. The first to fourth head chips are arranged at intervals in a second direction orthogonal to a first direction. A nozzle, of nozzles arranged in a second head chip N and used for printing, which is positioned closest to the one side in the second direction is referred to as a nozzle A. A nozzle, of nozzles arranged in a fourth head chip N and used for printing, which is positioned closest to the one side in the second direction is referred to as a nozzle B. The nozzle A is arranged closer to the one side in the second direction than the nozzle B and the first roller is arranged closer to the other side in the second direction than the second roller.
Claims12
A printer configured to perform printing on a recording medium, comprising:
- first nozzle groups corresponding to a first ink and arrayed at intervals in a second direction orthogonal to a first direction;
- second nozzle groups corresponding to the first ink and arrayed at intervals in the second direction at positions which are different from arrangement positions of the first nozzle groups in the second direction and are adjacent to arrangement positions of the first nozzle groups in the first direction;
- third nozzle groups corresponding to a second ink and arrayed at intervals in the second direction at positions respectively corresponding to the arrangement positions of the first nozzle groups in the second direction;
- fourth nozzle groups corresponding to the second ink and arrayed at intervals in the second direction at positions which respectively correspond to arrangement positions of the second nozzle groups in the second direction and are adjacent to arrangement positions of the third nozzle groups in the first direction;
- a first roller arranged to face one of the first nozzle groups in the first direction on one side of a second nozzle group N in the second direction, the second nozzle group N being a N-th second nozzle group of the second nozzle groups counted from the one side in the second direction;
- and
- a second roller arranged to face one of the third nozzle groups in the first direction on one side of a fourth nozzle group N in the second direction, the fourth nozzle group N being an N-th fourth nozzle group of the fourth nozzle groups counted from the one side in the second direction,
- wherein a nozzle A is arranged closer to the one side in the second direction than a nozzle B and the first roller is arranged closer to the other side in the second direction than the second roller, the nozzle A being a nozzle, of nozzles arranged in the second nozzle group N and used for printing, which is positioned closest to the one side in the second direction, and the nozzle B being a nozzle, of nozzles arranged in the fourth nozzle group N and used for printing, which is positioned closest to the one side in the second direction.
