Abstract

A justification system for use in a printer employing a continuous recording form. The justification system comprises a timing pulse signal generating system which generates timing pulses in synchronism with the traveling of sprocket holes of the continuous recording form. The timing pulses signals for commencing the printing on each printing segment defined on the continuous recording form and the timing for stopping the advancement of the continuous recording form are controlled based upon the above timing pulse signals. With this control, printing can be executed with a correct positional relationship with rules on each printing segment, even if the continuous recording form is set in the printer with a slight misalignment in the direction of the travel path of the continuous recording form or if the form itself has expanded or contracted in its longitudinal direction due to the effect of humidity.
