ABSTRACT:
Printer apparatus capable of varying direction of an ink droplet to be ejected therefrom and method therefor. The apparatus includes a printhead having a first side wall and a second side wall defining a channel therebetween having an ink body residing therein. The first side wall and the second side wall are selectively movable for asymmetrically pressurizing the ink body. Selective movement of the first side wall asymmetrically pressurizes the ink body to eject the ink droplet therefrom and out the channel along a first predetermined direction. Moreover, selective movement of the second side wall asymmetrically pressurizes the ink body to eject the ink droplet therefrom and out the channel along a second predetermined direction. A pulse generator supplies a first electrical pulse to the first wall and a second electrical pulse to the second wall, so that the first and the second walls are selectively moved in a manner providing for variable ejection direction of the ink droplets. Cut-outs between neighboring ink channels reduce mechanical cross-talk between channels, which cross-talk would otherwise interfere with precise ejection of ink droplets.
