The Epson T1291 black ink cartridge is filled with DURABrite Ultra ink that is designed to print both text documents and photos. The documents produced using this ink are crisp and suitable for business use while the photos are clear, bright and smudge resistant. Individual ink cartridges like these are great because you only need to replace the colour or black cartridge that has run out. You can buy this ink and the rest of the set online now and have them delivered to your door for free when you choose standard 3-5 working day delivery. If you need your ink sooner choose next day delivery that is available for a small additional fee.
