The printing process is maintained over a preset length area and breadth area of the ticket, and speed of rotation of the roller corresponds to the variable pulling speed when the ticket is pulled. The rotation of the roller is detected, and the printing process is controlled for positioning the printing head in the ticket based on the rotation of the roller.
