HP OEM cartridges cost more than they should, but the quality, longevity, and printer compatibility are invaluable. In the unlikely event of a problem, I know HP will take care of it without any finger pointing between suppliers. Peace of mind has a cost.
Just started using this toner - I can see it is bigger than the original cartridge. I hope the printer will last longer than this toner - I get many error messages and no support since it is over 1 year old.
