Can´t print with epson TM-T20II

I can print on Debian distro but not on Endless.
I just had to install the Epson drivers.

In endless I can’t run the installation script.
Is there any way to install Cup drivers manually?
Can they be copied to a specific folder?
On debian they seem to be in the opt/epson_pcs/ folder and in the var/epson_pcs folder
