What special about Epson SX515W setup-cable for wireless?

I am trying to re-setup my couple of years old Epson SX515W wireless printer for my son's university use. It has been installing the SX515W printer driver and scan-driver alright in my laptop, but it still prompts to fit the Epson so-called USB Setup cable previously provided by Epson, between my laptop's USB and Epson SX515W's Min-USB for completing its final phase of wireless detections. However as I couldn't find that Epson's Setup cable any more, I just use the ordinary USB-Min USB cable from the other PC, but it just couldn't work, i.e. my laptop couldn't detect my SX515W printer even though the USB-to-MiniUSB cable was connecting. So is the Epson's USB-Min USB cable SPECIAL, i.e. it might have "special-connectivities" not privided in the normal USB-Min USB cable?

Thanks

Not sure. Have you tried - https://www.epson.co.uk/viewcon/corporatesite/produc...

Most likely the manual setup. Maybe double check printer default IP / net isn't screwing with the setup?
