Yes, it can print duplex. Try installing new drivers.

Thanks everyone for the information. Seems to be a more complex matter...😒

I have Win, printer works perfectly, WiFi, duplex, with Epson app, everything great and easily explained during installation.

The printer does not have duplex.

According to Epson Europe, the box should be accessible. Operative word here as always: "should". See the following link with the images quite far down

The link concerns a different, more expensive model, but the printer driver is certainly similar.

I have the printer under Windoof. It's news to me that this works. I'll have another look when I get home.
