Abstract: An example disclosed method includes providing power transmissions from a power storage unit to a power converter of a printing device, the power converter to supply an available amount of power to a print mechanism, the print mechanism having separately controllable print elements; determining a required amount of power for an upcoming print operation that involves energizing the print elements, the print elements including a first group of the print elements and a second group of the print elements; when the required amount of power is less than or equal to the available amount of power, performing the print operation by simultaneously energizing the print elements; and when the required amount of power is greater than the available amount of power, performing the print operation by alternately energizing the first group of the print elements at first times and the second group of the print elements at second times.
