The UB-U04 / UB-U06 Powered USB Interface Card is designed to allow the conversion of an Epson TM series POS Printer with a swappable interface from Serial, Parallel, Ethernet, USB, etc., to Powered USB therefore eliminating the need for an external power supply. Conversion is simple for users with no knowledge of printers, requiring only two phillips screws to swap from existing interface to the UB-U04, UB-U06 Powered USB interface.
UB-U04 models work in many more printers than the UB-U06. The UB-U06 requires the printer to have USB built-in on the main board (e.g., the TM-T88V or TM-H6000IV). Your PC or POS System must have 24 volt powered USB Ports for this to work. You will also need a powered USB cable to connect the printer.
