Abstract
A printing device includes a first transporting mechanism driven by a first motor, a printing unit, a second transporting mechanism configured to transport the printing medium transported by first transporting mechanism and is performed image printing on a first surface thereof by the printing unit, to the first transporting mechanism. The first transporting mechanism includes first transporting rollers disposed at a position upstream of the printing unit, and further includes second transporting rollers disposed at a position downstream of the printing unit and configured to rotate in both directions. The second transporting mechanism includes third transporting rollers driven by a second motor and configured to transport the printing medium switched back by the second transporting rollers toward the first transporting rollers. A transporting force of the second transporting rollers is smaller than a transporting force of the third transporting rollers.
