1. An ink jet print head comprising: a substrate having a first major surface through which extends an ink aperture and on which is formed: a first primitive, said first primitive being comprised of a first set of current-controlling transistors, a, first terminal of each transistor of said first set being coupled to at least one address line in a first set of address lines; a second primitive, said second primitive being comprised of a second set of current-controlling transistors, a first terminal of each transistor of said second set being coupled to at least one address line in a second set of address lines, said second set of address lines being electrically isolated from said first set of address lines; whereby each transistor in said first primitive can be activated independently of each transistor in that said second primitive by way of control signals on at least one address line of said first and second set of address lines.
