I still have a problem with the USB port not being released after scanning, but discovered that if I powered the unit off and back on, port was released and I could print again.
BTW, I had deselected HPOJ and a couple of other things when I installed Fedora. They were installed anyway. Should I have disconnected the printer from the USB port before I installed Fedora or is this just a bug?
