you are a Fedora (9) user and try to put a remote HP scanner (in my case, it is inside a LaserJet 3055 All-in-One) to work, do not forget to install the separate scanner driver package libsane-hpaio. All the goodnes of the HP Linux tools and xsane ends in frustration (about the scanning part) if you fail to do so. Otherwise, I would like to state that I am pretty satisified with that particular device and its indifference regarding operating systems.
