With HP genuine ink cartridges, I know it will be a quality product every time. I don't have to worry about ink smudging during the print and I know the page count per cartridge is pretty much what is advertised. Past experience with off-market ink cartridges have resulted in ink smudging and much less printed pages. So even though the off-brand may seem cheaper, it can actually be a much higher cost due to less useable ink per cartridge. Best to stay with the genuine HP ink cartridges for your HP printer.
