Genuine OEM Samsung ProXpress M4020 ND Toners

For the M4020ND, MLT-D203U offers more rated pages than D203L or D203S. D203L sits between that option and the lower-capacity D203S. A larger-capacity black toner cartridge gives you longer between changes when you print frequently.

Toner Buzz carries genuine Samsung MLT-D203S, MLT-D203L and MLT-D203U as individual black toner cartridges. Start with how quickly you use toner: D203S offers the lowest capacity, D203L adds more pages, and D203U gives you the longest interval between changes among these options.
