Abstract
An apparatus addresses ink jet heating elements based on image data to cause ejection of ink droplets toward a print medium. The apparatus includes a controller for generating address signals, power signals, and first and second bank signals. The first and second bank signals, which are carried on first and second bank lines, alternate between on and off states. The first bank signal is off when the second bank signal is on, and the second bank signal is off when the first bank signal is on. The apparatus has m address lines and n power lines connected to the controller for carrying the address signals and the power signals. A print head has m.times.n number of first driver circuits, each of which is connected to the first bank line and to a corresponding one of the m address lines. The first driver circuits enable flow of a first driving current when the first bank signal and the address signal are simultaneously on on the first bank line and the corresponding address line. The print head has m.times.n number of second driver circuits, each of which is connected to the second bank line and to a corresponding one of the m address lines. The second driver circuits enable flow of a s…
