from the web interface ( as a normal every day user NOT AS ROOT- that will not work
click "add printer"
you WILL be asked for the root user and password in a pop up
password: ( the password you used )
then you can delete the installed settings and start fresh
but 99.99% of the time the auto detected settings " just work"
from the first post
It asked for some downloads which I did
odd almost all of the HP printers are in the cups software that was installed at the time of fedora being installed
there normally is nothing to download and install
And a usb HP laserJet printer "should" be auto detected and auto set up
with nothing to download and install .It "should " just work " out of the box
An idea ?
this might be what is causing some problems ? maybe?
was the printer connected to the computer when you installed fedora 17 ?
if not that would cause the printer to NOT be set up and CUPS to have been needed to be downloaded now
