The LTP1245 2“ direct thermal printer mechanism is designed for portable printing applications. This innovative product features a paper feed knob, “circular” type auto-cutter, and choice of curved or straight paper path orientation, for added design flexibility. The LTP1245 can also be configured the PT110P01 processor, supporting Serial and Parallel interface connectivity.

Product Highlights

  • Low operating voltage for longer battery life
  • Compact and light-weight
  • Paper feed knob model available
  • Straight and curved path models for maximum design flexibility
