for an Epson RX585, voracious ink, I regret that Epson (but is it the only one?) to sell product also expensive, especially for such a small capacity. Knowing that there are 6 cartridges and many cleanings are necessary because they become clogged, the cost for this printer page .. excess, even for a casual user. But I do not advise compatible inks, which can damage the printer. Only solution: pay ... or go to competition (eg laser).
