That's good. Try cheap cartridges. There's a reason they're a lot less than $. That's because they're terrible. The print quality is inconsistent and they just don't last as long as these HP branded cartridges. I didn't count. I don't need this when throwing away printed documents because the print quality sucks on unnamed cartridges. What about the price of the paper? That's a double whammy. Sometimes you really do get what you pay for. I tried these medium capacity cartridges to try and save $. I'll probably go back to high-yield HP cartridges, at least for black (for your most frequently printed black and white pages).
