l Bought all cartridges for an office jet pro 6978. approximately $100 dollars worth of ink. This is the 1st ink change for this printer which also was bought at office depot. Black ink cartridge is defective and will not print. Local store only offered to recycle it. For all the electronics and furniture I have bought from this store, it was like a slap in the face. Since office depot cant stand behind their products, I will just get my supplies elsewhere or online. Ordered new ink cartridge from HP since my son needs it to do his school work.
