Abstract
A thermo-sensitive recording apparatus individually controls the energization level of each of a plurality of heater elements formed on a substrate and constituting a thermal print head. In generating each energization level, the present and previous status of an individual heater element and selected neighboring elements are taken into consideration. Other factors combined in a selectively weighted manner include the latent heat of the individual heater element and its neighboring heater elements, the resistance of the heater element, the percentage of heater elements to be activated during the printing of a line, and the temperature of the substrate.
