Does anyone know how many average pages that a hp number 21 black ink can print out??

I have just bought a new black ink cartridge, and I am just wondering how many pages roughly that I should be able to get out of it before it runs out.


Thanks to all that answer.Does anyone know how many average pages that a hp number 21 black ink can print out??
You will be able to print roughly 190 average pages from an HP 21 cartridge. My printer uses that cartridge and that figure would be about right when you print mainly text.
