Probably something really simple I am missing here, but have spent a lot of time trying to get this to work.
New PC like 2.4ghz, and am trying to get this printer USB HP 900 all in one to install. It auto installs to a Dat01_001 port (not sure if that is exact but something really close to that). Anyways as a list of ports the USB is not listed, and it is listed in the device manager. So it auto installs and acts like it should work fine, but it does not print. Like I said probably something really simple in which I am missing. Been a long day though.
