If your HP printer not responding then there are a number of things that you can do from your end to tackle the situation. First of all, you need to make sure that it is connected to the power source. Then you should check if the HP printer and laptop/desktop are connected to the same internet connection or not.
This is a very basic thing that is why many people tend to overlook it. You can also try to get it to respond by switching it off and then waiting for a couple of minutes before you turn it back on.
