ABSTRACT:
A control device which controls the supply of energy heating elements of a thermal head. The control device to a memory includes for storing multiplication results as correction energy values of combinations of influence parameters, each of the influence parameters indicating a degree of influence caused by a reference heating element on a targeted heating element, and all energy values that can be supplied to reference heating elements. The control device also includes an address generation section for specifying a reference heating element that affects the targeted heating element based on printing data and generating an address based on a combination of the influence parameter of the reference heating element and the energy value that was supplied to the reference heating element and a memory control section for reading out a correction energy value from the memory based on the generated address.
