My EPSON PX710W (excellent printer!) Can work with either the T0801 or TO791. This is of course the same ink. Despite its slightly higher price, the TO791 seems to be more interesting than the T0801 because the first contains 11 ml of ink and the other only 7 ml. Make your account !! I adopts TO791 at current prices ... Obviously, it is the same for the other 5 printer cartridges.
