Hello I just bought an Epson EHT-40 and I'm not relly sure how I am supposed to access DOS on it. When I turn it on it boots in a System Menu but I still can't access DOS from there. If I turn it on holding MENU it first asks me for a password (I'm waiting an answer from the seller about that) and when I simply tap ok it boots to the same System Menu.
Any material (drivers, manuals) and infos about this machine will be really appreciated.
