Well, I purchased a new HP Officejet pro 8720 from amazon. All was good till I needed ink. No problem, just order it and install. Wrong....Seems HP sells the same printers in different parts of the world and they price there ink depending on where the printer was sold. Well, My printer was sold in Brazil, and the ink I was purchasing was USA ink. NOT compatible via software. I pitched the biggest *****, Till I got HP to reprogram my printer to USA standards AND got the free ink for life....
