    Works great
    Bought this to attach a UPS thermal printer to a new computer that doesn't have a serial port. Used with Windows 8.1no software needed. Just attached the cable, plugged in the printer and installed the printer drive.

    PROS: Small, easy to use.

    CONS: None.

    Works great. I recommend that you go here for the latest drivers
    Model is MCS7703

    Also, install the software FIRST, before pluging in the hardware! If you don't then you won't have the ability to change the COM port number! It will also not add a Feature tab in the device properties in the Device Manager.

    Again, install the software FIRST (OneSetup.exe) or you will lack the ability to assign a COM port number and use other advanced features.
