Before I fully immerse to studies of Nix package development, I would like to ask whether anyone has written a package for a proprietary CUPS driver of Epson Inkjet printers. There is an open-source variant of that called “epson-escpr” but this does not support duplex printing. Epson still offers a download of rpm and deb packages for my specific printer - Epson Stylus SX525WS - from the company website and it is, despite its age, still compatible with new Linux distributions.
A potential new development would include installation of binary closed libraries, which will be quite difficult for newbies like me.
I would appreciate any kind of help.
