Abstract
The temperature of heat elements of a thermal head can be controlled with high precision by a process with a low processor load. A printerthat prints on thermal roll paperbased on print data has a thermal headwith multiple heat elementsarrayed in a sub-scanning direction CR perpendicular to the conveyance direction F of the thermal roll paper. The printerhas a current control unitthat segments the heat elements of the thermal headinto plural blocks, and controls the energize timing of the heat elements in each block based on the number of heat elementsthat are energized in the thermal head
