Hello Adrian. Thank you, I have tested your guide.

The results:

With Windows install cleanup I have uninstalled the files described in the heading of the programme highlighted in blue in screen Annex.

Then I have checked in device Manager and not the result driver HP installed.

Therefore, I have selected "property" in the executable that I you ANNEX: is not present the voice that you say: "vista 64-bit" but the following headings: vista,vista sp1 and vista sp2: have selected run in compatibility with vista sp2.

I installed finally the drivers,
I have lit the printer and have connected to the PC but:


always the same error: "Windows is not able to recognize the device connected to your computer." "unknow device"
