Since an RSS composite code is made by combining an RSS bar code and a MicroPDF bar code, you’d think you would have to enable them both on the EZ and then under composite have it set to required.
But you actually just enable the RSS and then set composite to required and don’t enable MicroPDF at all.
For speed, put the EZ in fast linear and make sure the code is lined up. Create a 2nd IP database entry for standard mode just in case it’s not lined up.
