in Sierra Era i cant find the output to disc button,  thanks for your help

This function no have in Sierra embroidery software. You can using Embird  software - www.embird.com

I have a 15 yr old Brother 416 embroidery machine , cable USB converter and a laptop with  Windows 7 OS with 4 USB ports.  would like to hook laptop up to machine any ideas would be appreciated

I experience tell me this function (if you need special USB connection option)  not support. New embroidery machine have standard (inside/outside) flash. Easy for transfer and save embroidery designs to machine.
