Notes: 1. The signals in must be prepared by the user. 2. The pulse is indicated by a dot-dash line (*1) is generated for continuous printing. The next print cycle can start immediately after the leading edge of the timing signal Ts. 3. As shown by a dashed line (*2), the timing signal may go low at motor power-on or upon reception of a Print command. �9�
