The Epson 16XL ink cartridge, in magenta, yields approximately 450 pages. It's part of Epson's 16XL series, a high-capacity version that yields more pages per cartridge than the standard 16, reducing the frequency of replacements for regular printers. It's compatible with Epson WorkForce WF-2010, WF-2510, WF-2520, WF-2530, and WF-2540 printers, a range of multifunction devices designed for small offices and intensive home use. It's a preferred option for those who regularly print color documents on one of these WorkForce printers and want to reduce the frequency of cartridge replacements.
