Printing apparatus and method of controlling it

摘要

A printing apparatus (1) including a thermal head (15), a measurement device (41) that measures a temperature (T) of the thermal head (15) and a controller (40). The controller (40) controls a printing speed on the basis of the measured temperature (T) as measured by the measurement device (41), determines whether the measured temperature (T) of the thermal head is rising or dropping, compares a preliminarily determined first threshold value (T1) with the measured temperature (T) when the temperature (T) is rising, compares a preliminarily determined second threshold value (T2) with the measured temperature (T) when the temperature (T) is dropping, controls printing by reducing the printing speed when the measured temperature (T) is greater than the first threshold value (T1), and controls printing by raising the printing speed when the measured temperature (T) is less than the second threshold value (T2).
