Personally, I've never tested the cartridges which are standard brands, or those that can fill that are much less expensive but long term there may be t he bp on the printer. Mine works for ten years so I only buy official HP cartridges such as these and I am satisfied. I never tried to count the number of pages printed, but certainly a lot because I can print from 6 months to a year and one can say that I use almost every day either in printing or photocopying. I recommend these cartridges that have always been reliable and are about the same at a very decent rate on Amazon, which delivers within 48 hours pr mostly always quality packaging.
