well when looking at my ik levels coming up on my hp printer it doesn't show my ink levels now and has a explanation mark next to the colours now cos it doesn't register the iks so can't tell when will be running out as now finding out it isn't a proper hp ink cartridge and also has been refilled it seems so now didn't realise this as it never said on-line unlike others on-line so hope that my computer will be alright now.am pretty annoyed as should of said on-line all details about the cartridges cos now my printer isn't able to let me know now what it always has before.
