Know the name of a driver to use on the CUPS gui

I have this *Epson L355* printer and according to www.openprinting.org I need to use the epson-201207w driver; however, on the CUPS config panel at http://localhost:631, the list of drivers only displays names like *Epson E 300*, *Epson EM 900C*, etc, but not *Epson L355* nor even *Epson L300* is present on the list. I tried to investigate the "human-readable" form name of the said epson-201207w driver but I can't find anything. Is there a way to know, or at least guess it?
