Abstract
A line printer for printing successive lines of information on a ticket. As the ticket is guided toward ticket printing and advancing mechanisms, a first ticket sensor energizes a latch circuit and shifts the ticket advancing mechanism from a normally closed condition to an open condition. The ticket then moves freely into the printer to a predetermined position defined by a stop. A second ticket sensor at the stop is then actuated to close the ticket advancing mechanism and enable ticket advancement.
