  • Patent number: 7314262
    Abstract: A liquid ejecting apparatus of the invention includes a distance obtaining unit that obtains a distance between the nozzle of the head and a medium to which the liquid is ejected. The driving signal is a periodical signal including a first pulse-wave capable of ejecting a drop of the liquid having a predetermined volume at a relatively low speed, and a second pulse-wave capable of ejecting a drop of the liquid having the predetermined volume at a relatively high speed, the predetermined volume corresponding to a predetermined level data. The driving-pulse generator is adapted to generate, when the selected level data is the predetermined level data: a driving-pulse including only the first pulse-wave when a distance obtained by the distance obtaining unit is not less than a predetermined value; and a driving-pulse including only the second pulse-wave when the distance is less than the predetermined value.
