ABSTRACT:
There is provided a liquid drop discharging device including: a liquid drop discharging head that discharges liquid drops onto a recording sheet; a discharged region computing section that, on the basis of inputted image data, computes a size of a region where liquid drops are to be discharged on the recording sheet by the liquid drop discharging head; a margin proportion computing section that, on the basis of the computed size of the discharged region and a size of the recording sheet, computes a proportion of a margin of the recording sheet; and a determination section that, when the computed proportion of the margin is less than a predetermined margin proportion, determines that sheet curling will occur at the recording sheet on which an image is recorded by liquid drop discharging of the liquid drop discharging head.
