摘要
Provided is a thermal print head having a memory for storing resistance values of heaters to compensate for an energy drift of the thermal print head. The thermal print head includes a plurality of heaters for applying heat to a medium. A heater driving unit drives the heaters according to received data. A memory stores resistance values of the heaters. Accordingly, the thermal print head having the memory which stores resistance values of heaters compensates for an energy drift of the thermal print head by using the resistance values of the heaters stored in the memory without individually measuring the resistance values, and therefore can achieve uniform print quality.
