Abstract
An airline ticket printer includes a thermal printer engine with a platen and a print head. A gap is maintained between the platen and the print head except when a ticket is present for printing. A ticket is fed toward the gap and the feeding of the ticket is sensed. At a timed interval after sensing the feeding of the ticket, the print head is moved toward the platen by a stepper motor so that the ticket is engaged between the print head and the platen.
