This is a 6ft (1.8m) black USB cable for connecting an Epson POS receipt printer to a host PC or till system, matching the standard connection length most Epson TM-series printers ship configured for out of the box. It is a straightforward USB-A to USB-B (or USB-A to USB-C, depending on the specific printer model) connector cable with no electronics of its own, intended as a replacement or spare cable for an existing POS setup rather than a new capability.
