ABSTRACT:
In a printing control device for a thermal printer, a character read out from a character buffer for storing characters to be printed is supplied to a decoder and is then output from a character generator as a dot signal. In response to the dot signal from the character generator, an on-time preparing circuit outputs an on-time signal having a time duration determined by the number of dots associated with the dot signal or by the number of characters determined by the number of dot patterns. A voltage is applied to printing elements of a printing head for performing a printing operation for a time period determined by the duration of the on-time signal from the on-time signal preparing circuit.
