Comments about Okidata Black Toner Cartridge for B4100- B4200 and B4300 Series:
I used to buy after market cartridges, but they do not last as long and the print quality is obviously not as good. Also the after market cartridges will leak into the printer causing jamming of the paper due to misfeed of the rollers. After market maybe cheaper but it is not worth it, raegardless of the printer you are using.
