Methods and apparatus for supplying power to a printer
First Claim
1. A printing device capable of obtaining power from a power storage unit, the printing device comprising:
- print elements configured to generate indicia on media, the print elements including a first group of the print elements and a second group of the print elements separately controllable from the first group of the print elements;
a power converter configured to be coupled with a power storage unit, the power converter to supply an available amount of power from the power storage unit to the print elements;
a controller configured to determine a required amount of power for an upcoming print operation that involves energizing the print elements; and
a printer control and image generating circuit in communication with the power converter, the printer control and image generating circuit configured to;
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 first and second groups of 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 energizing the second group of the print elements at second times.

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.

7. A method for providing power to a printing device, the method comprising:
-
providing power transmissions from a power storage unit to a power converter of the 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, using a logic circuit, 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 different than the first times. - View Dependent Claims (8, 9, 10, 11, 12)

13. A controller in communication with a print mechanism having print elements, the controller comprising:
-
memory including machine-readable instructions; and a processor to execute the instructions to cause a printing device to; determine 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; determine an available amount of power from a power storage unit; when the required amount of power is less than or equal to the available amount of power, cause the print mechanism to perform the print operation by simultaneously energizing the print elements; and when the required amount of power is greater than the available amount of power, cause the print mechanism to perform 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 different than the first times. - View Dependent Claims (14, 15, 16, 17)
