Abstract
A method of correcting a conveyance error of a continuous sheet having a train of segments each including a respective segment mark and being conveyed for printing in accordance with the number of steps is disclosed. The method counts steps between consecutive segment marks during conveyance of the sheet to thereby output an actual number of steps, compares the actual number of steps with a preselected number of steps determined by a distance between the consecutive segment marks, and corrects, based on the result of comparison, the start of a new line at even positions of a single segment during subsequent conveyance. An apparatus for practicing the method is also disclosed.
