Should I refill the black?
I got a HP officejet 4315 All-in-one printer which works fine but the 21 black is empty(checked under the label too)
And the reason i am unsure about refilling the black is the printer was from a garage of one of my neighbors who gave it to me
and it was in a box of thier daughters stuff possibly from college and was gonna be in the trash anyway and god knows how long its been there
Is this a good question?
