Abstract
The present invention relates to a method of erasing printing by a thermal transfer printer which is capable of erasing printing on paper. A printing area is divided into a plurality of small areas extendedly disposed in the direction in which a carriage moves. These small areas are divided into a plurality of erasure units made up of a plurality of small areas spaced apart from each other. The erasure operation is divided into two or more operations performed on each unit whereby erasure of printing is reliably performed and damage to paper is suppressed to a minimum.
