A power source for a printer has a power source unit (15) for supplying power to the printer and lead wires for electrically connecting the power source unit to the printer. The power source unit (15) includes a compensating circuit (4, 5, R3, R4, R5) for compensating a reduction in voltage applied to the printer from the power source unit, and the compensating circuit (4, 5, R3, R4, R5) detects a load electric current supplied to the printer only within the power source and is constructed such that the reduction in voltage is compensated in accordance with the load electric current. <IMAGE> |
