That sounds like two subjects. Thermal transfer CD printers don t use inks, they use a wax/resin on a ribbon. So there is nothing to try in an Epson.

Along the lines of my last post has anyone tried the thermal transfer inks that they use on professional CDs. I m not sure how much the printers are but I m
