The Epson T266 is a black pigment-based ink cartridge designed specifically for use with the WorkForce WF-100 and WF-100W portable printers. With a capacity of approximately 5.8 ml, this cartridge allows you to print around 250 pages, making it a practical choice for those who need a reliable mobile printing solution for documents on the go. Because it uses pigment ink, the text remains sharp and resists smudging, which is particularly useful for professional reports or invoices. The compact design of the cartridge ensures it fits seamlessly into your device, while the lightweight packaging makes it easy to store as a spare in your bag.
