Abstract
A technique is provided that reduces the occurrence of a difference in print resolution between an upstream ejector and a downstream ejector due to expansion and contraction of a recording medium. An inkjet printing apparatus includes four heads arranged in a transport direction and four ejection controllers that control the four heads, respectively. Each ejection controller includes an ejection timing generator that generates an ejection timing signal for causing the head that is controlled to eject ink toward a target portion of a recording medium, an expansion/contraction amount estimator that estimates the amount of expansion and contraction in the target portion, and a correction information generator that outputs, to a downstream ejection controller, correction information that includes the ejection timing signal and expansion/contraction amount information indicating the amount of expansion and contraction.
