When i log in, I notice something try to appear on my dock. It doesn't even seem to fully open, sometimes the dock just expands a little bit. Once, when it stayed a little longer, I was able to move my cursor to it and it said the thing was called pipedaemon. I did some research, and found it was part of the HP printer software, but I still thought it odd. So is this thing just a harmless piece of software that I actually need, or is it something I should get rid of?
