Ok. Let's check then...

1. You have downloaded ESC/P-R Driver (generic driver) 1.7.6 for printer and 
All-in-one package 3.61 (imagescan, package for Ubuntu 18.04) for scanner from 
https://download.ebz.epson.net/dsc/search/01/search/?OSC=LX

2. All these packages were installed without problems and printing works.

3. The device turns on, the cable is not broken but it cannot be detected even 
by dmesg when connected to your computer.

Right?
