Hey There, I am Sofia Carter. Your hp printer keeps going offline if it can't effectively interact with your laptop or PC. There are a few things you can do to get it back online on Windows 7, Windows 8, Windows 10, or Mac. As a rule of thumb, HP printer offline difficulties are caused by blocked paper in the printer's paper path, faulty connections, outdated firmware, and so on. The device can be reinstalled and/or restored to its default settings.
