I've got something that might work. Can't test it as I haven't got that kind of printer. It's based on this.
You'll likely need to install a bunch of things first
sudo apt install lsb-base build-essential automake autoconf system-config-printer libcups2-dev libcupsimage2-dev cups alien
Download the epson-inkjet-printer-201401w-1.0.0-1lsb3.2.src.rpm
, then extract it:
rpm2cpio epson-inkjet-printer-201401w-1.0.0-1lsb3.2.src.rpm | cpio -idmv
Extract the filter:
tar xvzf epson-inkjet-printer-filter-1.0.0.tar.gz
Build it:
cd epson-inkjet-printer-filter-1.0.0
libtoolize --force --copy
aclocal
autoconf
automake --add-missing
./configure --prefix=/opt/epson-inkjet-printer-201401w
make
sudo make install
cd ..
Now extract the other archive, epson-inkjet-printer-201401w-1.0.0.tar.gz
and move the support files into place:
tar xvzf epson-inkjet-printer-201401w-1.0.0.tar.gz
sudo mv epson-inkjet-printer-201401w-1.0.0/ppds /opt/epson-inkjet-printer-201401w
sudo mv epson-inkjet-printer-201401w-1.0.0/watermark /opt/epson-inkjet-printer-201401w
Now try installing the printer again - you should be able to use the graphical printer configuration. Again: I don't know if this works, as I don't have the printer, but at least it builds the binary filter and puts the PPD files where the system might expect them.
