Are you facing trouble to connect HP printer to computer system through a USB or wireless connection? Before looking to the fixes, you should be aware of the reasons behind the occurrence of this error. You might be attempting to connect your computer system and the printer to two different wireless networks. Second reason could be that you are entering the wrong password of your wireless network while connecting your printer to it. Furthermore, your printer might not be placed in the proximity to your wireless router. Another possible cause could be with the wireless network settings; it might not be discoverable to the nearby devices. If everything seems fine and you are still not able to connect printer to your Windows or Mac device, then connect to HP support professionals over call, email or through live chat. A technician will provide you with the most viable solution.
