摘要： One of printing modes including a first mode in which printing is performed by an even number of scans and a second mode in which printing is performed by an odd number of scans, the odd number being three or more, is executed. In the first mode, printing is performed using a first mask pattern in which the nozzle array is divided into a plurality of blocks each including a first number of continuous nozzles and an ink ejection area or non-ejection area is set for each of the blocks. In the second mode, printing is performed using a second mask pattern in which the nozzle array is divided into a plurality of blocks each including a second number of continuous nozzles, the second number being less than the first number, and an ink ejection area or non-ejection area is set for each of the blocks.

摘要： A liquid ejecting apparatus includes a liquid ejection head, a circulation control section that controls a circulation operation of circulating the liquid in the first individual flow path, and a minute vibration control section that supplies a drive signal having a first waveform to the first piezoelectric element so as to control a minute vibration operation of causing the liquid in the first nozzle to vibrate to such a degree that the liquid is not ejected from the first nozzle. The circulation control section starts the circulation operation at a first time, and the minute vibration control section starts the minute vibration operation at a second time later than the first time.

摘要： A liquid ejecting apparatus includes a nozzle for ejecting a liquid, first to fourth pressure chambers communicating with the nozzle, first to fourth driving elements provided corresponding to each of the first to fourth pressure chambers, and a control section that controls the first to fourth driving elements. The control section is capable of executing a first ejection mode in which all of the first to fourth driving elements are driven to eject a liquid from the nozzle, and a second ejection mode in which only some driving elements among the first to fourth driving elements are driven to eject a liquid from the nozzle.

摘要： A liquid discharging apparatus has a switch control circuit that controls whether to cause each of a first switch circuit, a second switch circuit, a third switch circuit, and a fourth switch circuit to output a driving signal. The switch control circuit has a fifth switch circuit, a sixth switch circuit, and a seventh switch circuit. The fifth switch circuit switches between output of the first data to the second switch circuit and output of the second data to the second switch circuit. The sixth switch circuit switches between output of the first data to the third switch circuit and output of the third data to the third switch circuit. The seventh switch circuit switches between output of the first data to the fourth switch circuit and output of the fourth data to the fourth switch circuit.
