<p>A die for a thermal drop-on-demand fluid-ejection device includes thermal firing resistors, low-side switches, and high-side switches. The thermal firing resistors are organized over resistor groups such that each thermal firing resistor is located within only one of the resistor groups. The resistor groups are lesser in number than the thermal firing resistors. Each thermal firing resistor has a first end and a second end. The low-side switches are equal in number to the thermal firing resistors. Each low-side switch connects the second end of a corresponding thermal firing resistor to a low voltage. The high-side switches are equal in number to the resistor groups. Each high-side switch connects the first ends of the thermal firing resistors of a corresponding resistor group to power providing a voltage greater than the low voltage.</p>
