How much do you print a cartridge on a sheet of paper? And do you recommend hp m28a?

Please help which brand and model of the powder? Any recommendation ?

thanks

Thank you very much I have done just like you. But do you know why the lamp still lights up on my printer? and when I log in to the data and on the Hp app, there is still some toner left.

Where can I buy toner powder from?
