cannot plugin Wi-fi printer Epson L4160

Installed official Epson drivers for L4160 Wi-Fi printer. I can add it in Control Center though it doesn't work - when trying to print test page or to print from other applications it raises errors like "can't connect to printer", etc. Epson drivers from Ubuntu repo don't work either.
THE SAME Epson drivers work flawlessly on Fedora on another machine WITH THE SAME PRINTER in the same local network.

Some messages I got from journalctl -f :
