Abstract
A thermal printer includes a thermal head having n heating elements arranged at a preset pitch D1 in a line, a memory including a first memory area storing a plurality of high speed printing character data each column of which is composed of n-bit data and a second memory area storing a plurality of high resolution printing character data each column of which is composed of m-bit data (m>n); and printing control circuit which reads out the m-bit data of each column designated by the input character code data from the second memory area in accordance with the high resolution printing mode designation data, and drives the thermal head in accordance with the m-bit data read out. The printing control circuit reads out the n-bit data of each column designated by the input character code data from the first memory area in accordance with the high speed printing mode designation data and converts this n-bit data into the N-bit data (N>n) and drives the thermal head at an average dot pitch D2 (D2 is larger than D1 and differs from the integer multiple of D1) in accordance with the N-bit data.
