An integrated printhead which includes an M row by N column array of groups of ink jet elements wherein each group has a unique row and column address; a first addressing control coupled to the array of groups for selecting one of the M rows of the M row by N column array of groups of ink jet elements; and a second addressing control coupled to the array of groups for selecting one of the N columns of the M row by N column array of groups of ink jet elements. One individual group of ink jet elements is addressed by the first addressing and the second addressing controls. In a specific embodiment a third dimension of addressing is provided by a plurality of address line selects that are coupled to the ink jet elements in each group. In an alternate specific embodiment the resistance between the first addressing means and the second addressing means for each group of ink jet elements can be adjusted to balance the energy dissipated between the groups of ink jet elements. The unique three dimensional addressing system provides for high density integrated printheads that have significantly fewer interconnect pads, which will minimize costs and increase reliability.
