I can't tell you how much I hate my Epson printer. WiFi sometimes works, sometimes not. A gear icon appeared on the Wi-Fi screen; Whatever I try, it won't work. Delay at Epson: no thanks. I've been transferred several times. I still don't understand what went wrong! This cable has arrived; I grabbed a flashlight to stick it in my back. PERFECT. Epson is one of a group of outsiders who have decided not to include a cable with this printer. Imagine a non-technical 80-year-old trying to set up Wi-Fi. Ridiculous. So buy this for your Epson printer and never curse your printer again! :)
