My printer (Epson ET-5180) worked perfectly when it was connected to my computer via a USB cable. As soon as I added Wi-Fi to it so that I could get it to print from my laptop, I started having the issues of the computer going offline and that stupid error message over and over again. I decided to discontinue using the Wi-Fi option and just send any document from my laptop to my desktop, where I could print it without any problems.
I hope this helps.
Sincerely,
Richie Shannon
