Thermal printer for printing continuous media with outer holes has multiple tractors to enable uninterrupted printing for periods of around 8 hours and a controllable cutter so that single sheet output is possible

摘要

Thermal printer with a tractor device for continuous media with side holes. The traction device comprises one or more tractors for feeding continuous material, 2 or more counter sensor in the outer hole region so that they can recognize the direction of paper movement and generate control signals for the friction drive. One or more tractors can be taken out of the feed process so that paper can be changed over. A controllable knife can be used to cut off individual sheets of a defined length.
