Abstract

PURPOSE: To optimize print impact and improve print speed by controlling at an optimal value a printing head drive pulse width, a drive current and a relative feed speed of printing paper proportionately in accordance with the variations of printing paper thickness and printing head drive voltage.
CONSTITUTION: A microprocessor (hereinafter called mp) 1 reads a drive voltage V of a head driver 8 which is applied through a voltage detection circuit 5, so that the mp reads the thickness t of a form which is output by a form thickness detection circuit 6. Following this process, these values V, t are converted to drive currents I1, I2, head speeds V1, V2 and drive pulse widths τ1, τ2 respectively. In addition, based on I1, I2, an optimal drive current set value I0 is sought by drawing a drive current set table prepared before-hand. On the basis of τ1, τ2, an optimal pulse set value τ0 is sought from the table. Likewise, based on V1, V2, an optimal head speed set value V0 is sought. This value is output to a current control circuit 4, a pulse generation circuit 3 and a speed control circuit 2.
