According to HP, and HP software that gets installed for a printer that could be connected via a network (either wired or wirelessly) will install HPSETUP just-in-case ... it's how HP keeps an eye out for a wireless printer. I think they are using it as a network listening device. I use HP printers over a wired network and the software always installs HPSETUP. I believe HP desktops and laptops come preloaded with this software as well.
