HP is a detestable retailer: they force HP printer owners to buy HP only cartridges, which prices are OUTRAGEOUSLY high! If you go on Amazon and buy a cartridge from another suppliers, those horrible people from HP will forbid you to use your printer! I HAVE NEVER SEEN SUCH RESTRICTION OF TRADE, AND ABUSE OF DOMINANT POSITION AND POWER, FROM A RETAILER. HP should receive a MASSIVE FINE for acting in such an anti-competite manner like this. Also, their customer service is horrendous and useless, even worse than Applecare, which is difficult to achieve, frankly. HP is horrible and should stop trading all together.
