PROBLEM TO BE SOLVED: To provide a dot line printer which can prevent inconveniences such as deviation of a stopping location of paper due to printing load, increase in strike sound of printing elements, and soiling of the paper with ink, because when paper winds on a platen having a flat strike surface, the paper is lifted from the strike face of the platen due to the rigidity of the paper, the dot line printer being produceable at a much lower cost than a dot line printer having a platen having a curved strike face with a predetermined round curvature, to thereby bring about advantages of low costs and high reliability. SOLUTION: The dot line printer includes the platen having a paper guide in a paper carrying direction and the flat strike face, and a paper feeding mechanism for feeding the paper along the paper guide which is arranged at a predetermined incident angle and a predetermined outgoing angle with respect to the platen such that the paper winds on the platen with the predetermined round curvature. The dot line printer allows the paper and an ink ribbon to be arranged between the printing element and the platen, and carries out printing by a hammer bank. Herein upper and lower edges formed on a flat portion of the platen in the paper carrying direction are set on the circumference with the predetermined round curvature. COPYRIGHT: (C)2007,JPO&INPIT
