I have plugged a brand new posbox into my router via data cable (yellow and green lights are solid on either side of the data port on the posbox).
I have plugged a working TM-20 Epson printer into the posbox (via usb) and left it for hours... no status receipt ever prints as described in the installation guide.
I can see posbox as a wifi option.
I have tried unplugging and turning off everything and it makes no difference.
Any ideas??
