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 with either the IF1101 interface board or the PT110P01 or PT120P02 processor, each 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
