Seiko LTP5446B-C832 Thermal Print Head IF5003-02B Controller Board 120V Power

Seiko LTP5446B-C832 Thermal Print Head IF5003-02B Controller Board 120V Power

This is a matched set of Seiko thermal printer components: the LTP5446B-C832 thermal print head mechanism, the IF5003-02B controller board, and a matching 120V power supply. All three pieces were removed from brand-new, unused portable printer kits that were torn down before ever being put into service, making this a genuine new old-stock set for anyone building, repairing, or replacing components in a compatible Seiko thermal printer system.

Applications

The Seiko LTP5446B series is a line of direct thermal print head mechanisms used in compact and portable receipt, ticket, and kiosk printers. Thermal print heads of this type heat a resistive element array directly against thermal paper to produce an image without ink, ribbon, or toner — making them standard in point-of-sale terminals, portable receipt printers, label printers, and embedded kiosk printing systems. The IF5003-02B controller board manages motor drive, paper feed logic, and serial communication with a host system via the DB9 port. Sets like this are used by OEM integrators building custom printer systems, repair technicians replacing failed print head assemblies, and engineers developing embedded printing solutions. The LTP5446B-C832 print head and IF5003-02B controller are matched components intended to work together as a drop-in printing engine.
