The mileage on this printer is so bad. I put cartridges in for £70 and use them up within the month. I realize that full page photo is expensive, but seeing as how it is done in "normal" quality on "normal" paper I would have expected more.
Most recent change is that some tiny bit of plastic broke off. The piece of plastic holds a tiny spring that in some way is needed for the cartridge to align, and get recognized by the printer. The result of this, is that the printer is now bricked( or in for repairs, I cannot imagine what parts cost when supplies are an arm and a leg..)
Finally, the reason why I bought a HP, was to have the print-heads replaced with every cartridge, to avoid the endless clean cycles I have come to hate from owning Canon printers. Well in this particular case, cleaning was ALL THE TIME!
TL;DR: Last HP product.
