摘要： A method of driving a thermal printing head includes expanding the printing time for a line which follows successive non-printed (blank) lines. In this manner, deterioration otherwise caused in the print density can be avoided without employing an auxiliary heater for the thermal head. Instead of expanding the printing time, the applied voltage may be increased to achieve the same result.

摘要： Each picture element is made to correspond to a plurality of dots and the ratios of printing energy corresponding to respective dots in each picture element are determined to correspond to respective tones. The heat accumulation state of a heat generating member corresponding to a picture element to be printed is detected from the tones of picture elements about the picture element to be printed for controlling the printing energy supplied to the heat generating members corresponding to respective dots of the picture image to be printed in accordance with the printing energy ratio and the detected state. With this method it is possible to provide a half tone print having uniform high quality regardless of the tone of a previous line and tones of surrounding picture elements.

摘要： A printing method is shown in which printing quality is improved when superimposed thermal-transfer recording is performed. According to the present invention, at least one of a plurality of thermal-transfer media is made of a material of different thermal characteristics from the remaining media. Different thermal-transfer media thermal characteristics are obtained by changing the thickness, melting point or viscosity of the thermal-transfer ink on the thermal transfer media, or by changing the thickness, quality of material or density of the base material of the thermal-transfer media.

摘要： A thermal head drive circuit with the input connected to a source of printing data and the output connected to a thermal head including heater elements, so as to improve the picture quality of a thermal head recording apparatus for printing successive lines. Improved picture quality is effected by using data from previously printed lines to compute a corrected pulse energy for the line being printed. The circuit uses a heat storage state operator for operating the heat storage state of each of the heater elements constituting a thermal head, a pulse energy operator for computing a printing pulse energy to be applied to each of the heater elements, a memory for storing the electrical pulse energy used in the previously printed line, and a counter to count the number of dots on the line to be printed. The pulse energy operator uses data from the heat storage state operator, the counter, and from the memory which has data on the pulse energy used in previously printed lines. The output of the pulse energy operator is connected to a pulse generator which is used to drive the heater elements of a thermal head.
