Everything on my computer and printer was working fine. I have a Dell computer and an HP printer. I could print, copy and scan just fine. Then all of a sudden when I saved a couple of documents, the letters DESKTOP GSUUSUU were added to the end of the document name. Example: Letterhead - DESKTOP - GSUUSUU. I have no idea why that happened or what it means. After that started happening, now I can still print and copy just fine. But when I try to scan, the window on the printer shows DESKTOP-GSUUSUU (USB) as the name of the printer, and it won't scan because that is not my printer. My actual printer does not show up on the printer list in the printer window , so it is not recognizing my printer. I would like to know three things: Why did DESKTOP-GSUUSUU start showing up as part of the document name, and why does DESKTOP-GSUUSUU show up in my printer window, and my actual printer does not show up..
