Print Rite Samsung MLT-D203-U

The MLT‑D203U toner is Samsung’s ultra high yield black toner cartridge with around 15 000 page yield at ~5 % coverage — significantly more than standard or high‑yield versions like MLT‑D203S (3 000 pages) or MLT‑D203L (5 000 pages)

Toners in the D203 family (including U, L, E, and standard D203) are designed to fit many Samsung ProXpress and Xpress monochrome printers such as:

• Samsung ProXpress SL‑M4020 / SL‑M4020ND / SL‑M4020NX

• Samsung ProXpress SL‑M4070 / SL‑M4070FR / SL‑M4070FX

• Older variants also work in SL‑M3820, M3370, M3870, etc., depending on model and toner type.
