What are these folders and processes?

I have a HP Photosmart C4580 Printer and I have the software for it installed on my Mac. However, I had a HP Photosmart 7760 Printer and I do not think I removed its software fully. I have these HP processes and these HP folders running at startup and I was wondering whether they are for the 7760 Printer or the C4580 Printer. What do they do? Thanks.

PS- The first screenshot are the processes and the second screenshot are the folders.
