I got this printer/scanner with a new HP dv6 running Windows 8, and used that computer and Windows 8 to set the printer/scanner up. It installed seamlessly on my WLAN, and has worked perfectly printing and scanning over my WLAN in the week that I’ve had it. (I have not yet used ‘ePrint’ so I can’t comment on it.) I have only printed and scanned documents on standard paper so far. I haven't tried to print photographs, so I can't comment on that, either.
Once the printer/scanner was running on the machine I used to set it up, I then installed the drivers (from the online installation site) on an older HP dv7 (Windows 7) computer, and that installation went perfectly as well. I didn’t have to involve the printer at all with the dv7 setup.
It would be nice if the scanner offered the option of adjusting the PDF (and perhaps other format) scan resolution on the printer/scanner itself rather than having to do that from the software on the computer, but that is a minor inconvenience.
There have been reviews of this printer/scanner that indicated that it was difficult to set up, was flimsily-constructed, and jams. I have had none of those problems, and it seems sturdy enough to me.
