I struggled hour, the printer is not recognized by Window 7, and with a message on my computer that drivers could not be installed. Went to the HP website to find solution. Usual bazaar. Finally my old printer walking again, I took the connecting cable of the old printer, and miracle, the installation was successful. Conclusion: I had bought with the printer, the connecting cable with the computer that appears in the bottom, and it was he who was failing! May this serve .... An hour galley.
