  "textContent": "A power supply for a portable printer, including an apparatus generating a main driving voltage and a driving voltage for driving a portable printer using the external alternating current voltage if an external alternating current voltage is applied, and which generates a main driving voltage and a driving voltage for driving the portable printer using an internal battery in the portable printer if no external alternating current voltage is applied. The power supply includes the reference DC voltage being lower than the first voltage. By lowering the reference DC voltage of the power supply, it is possible to substitute various circuit devices included in the power supply with low-cost components, thereby reducing a cost of the power supply.",
