I find the hp-systray annoying too. Especially since I found it just now using 100% CPU (at the same time NOT appearing on screen. I had to kill it the process from the command line. (It didn't help that under top, it listed as "python" not as "hp-systray", but that's bug #463203)
On the other hand I do use a HP printer, so I'm quite happy to have hplip installed and hp-systray available when I need it. The reason it pops up automatically is that it's registered in the start-up list for Gnome sessions. I think this is done by the hplip-gui package, via /etc/xdg/autostart/hplip-systray.desktop (so it should affect all desktop environments that support the FreeDesktop format, not just Gnome). I guess it makes sense for hplip-systray.desktop to be enabled at start-up (otherwise, "why install it?"), though this question is debatable. Either way it's a simple matter to disable the automatic hp-systray from the Gnome preferences: System->Preferences->Sessions, in the "Startup Programs" tab, unclick the "HP System Tray Service", and then the annoying little hp-systray will not bother you again.
