USB ultimately failed with our Z3200 in OSX. HP conceded that USB connection prevented the HP Printer Utility from working in some cases, and I was told that they, HP, did not know why USB failures occurred. I had used an USB connection for some months when the failure arose. Enet resolved the problem, as HP said it would. Since the networked connection was trouble free, and since it provided other advanteages, I never pursued the USB idea again.
I have no idea about the Windows world.
