Abstract
Official abstract text for this publication.
A thermal printer includes: a plurality of heat elements that are to be heated by applying an electrical power; a printing controller that applies a first electrical power to heat elements not to be used for printing, the first electrical power depending on the number of heat elements not to be used for printing among the plurality of heat elements; and a thermal head that prints using the plurality of heat elements.
First claim
Opening claim text (preview).
What is claimed is: 1. A thermal printer comprising: a plurality of heat elements for printing; and a printing controller configured to apply a first electrical power level to at least a first heat element of the plurality of heat elements, the first heat element to be in non-use in a printing, the first electrical power level being lower than a second electrical power level applied to at least a second heat element of the plurality of heat elements in the printing, the second heat element to be in use in the printing, wherein the printing controller is further configured to calculate the first electrical power level by dividing a remainder power number by a total number of heat elements of the plurality of heat elements to be in non-use in the printing, the remainder power number being obtained by subtracting a total amount of power to be applied to the heat elements of the plurality of heat elements to be in use in the printing from a fixed total amount of power to be applied to the plurality of heating elements for printing. 2. A thermal printer comprising: a plurality of heat elements for printing; and a printing controller configured to apply a fixed total amount of power to the plurality of heat elements during a printing, wherein the printing controller is configured to apply a first level of power to each heat element of the plurality of heat elements that is to be in use during the printing and apply a second level of power to each heat element of the plurality of heat elements that is to be in non-use in the printing, wherein the second level of power is lower than the first level of power, wherein the printing controller is configured to calculate the second level of power by dividing a remainder power value by a total number of heat elements of the plurality of heat elements that is to be in non-use in the printing, the remainder power value being obtained by subtracting a total of amount of power to be applied to the heat elements of the plurality of heat elements that are to be in use in the printing from the fixed total amount of power.
