    摘要: A thermal recording apparatus operates to efficiently utilize a smaller capacity power supply by the provision of a capacitor in parallel with the power supply source. The capacitor is discharged during printing cycles and is recharged in the interval between the end of one line printing operation and the beginning of the next. This interval is increased in proportion to the percentage of black bits printed in a given line, such that the capacitor may be sufficiently charged and the power supply efficiently used.
