When I go to print, an error message comes up saying no printer is connected. However, I've installed the software for it, tried to reinstall it but it told me it was already installed. When I use the HP Diagnostics, it tells me that the device is working properly. When I check Device Manager, there are all kinds of funny looking fork shaped symbols with similar variations of "Dot 4 HPZ12" beside them.
What does it all mean and how do I get my apparently installed printer to function properly.
