Inventor： Lawrence H. White ,  Thomas J. Cardinali ,  Michael Hager

IPC: B41J2/14 ,  B41J2/16 ,  B41J2/175

Abstract: Printheads and methods for forming printheads are described herein. In one example, a printhead includes a single resistor window in a conducting layer within the printhead. The printhead also includes a number of resistors formed in a resistor film deposited over the single resistor window. The resistors have two different widths, and each of the two different widths ejects a different droplet size when energized.
