PURPOSE:To prevent overlap printing, to assure printing quality and to shorten a printing time, by dividing a residual printing pattern into plural times to carry out printing when a power source is lowered by overload during pattern printing at every line of a serial dot printer. CONSTITUTION:When a power source voltage detecting circuit 11 is connected to CPU and power source voltage is lowered to a threshold value or less because of overload, the information of this state in sen to CPU10. The printing data from CPU10 is sent to an odd number printing control circuit 13 and a dot of an odd number is printed at every each timing after this point of time. After the final timing of this line, the timing is changed over to even number dots and printing data is sent to an even number printing control circut 14 to print a dot of an even number at each timing. |
