A printer includes a first ink-jet head which is fixed, and a second ink-jet head which is movable selectively to a first position which is opposite to an upper surface of a recording paper by an reversing-mechanism, and a second position which is opposite to a lower surface of the recording paper by the reversing-mechanism. Accordingly, it is possible to carry out printing on both surfaces of the recording paper, and it is possible to realize a high-speed printing and a high quality printing at the time of single-face printing. |
