PROBLEM TO BE SOLVED: To make it possible to suppress positional deviation by contriving a manner of correction.SOLUTION: A positional deviation amount calculation part 33 calculates a deviation amount due to skewing of a continuous form paper WP is calculated with respect to recording positions of a first image and a second image acquired by a recording position acquisition part 31. In the case that there is a remainder when a displacement amount is divided at a constant interval, a positional deviation interpolation image conversion part 35 performs weighting according to the remainder with respect to the second image and performs conversion into a positional deviation interpolation image which is deviated in a skew direction of the continuous form paper WP. Since a positional deviation interpolation image is made by weighting according to the remainder, a positional deviation can be fully suppressed irrespective of skew amounts, and lowering of a printing quality can be suppressed.SELECTED DRAWING: Figure 1 |
