Check the connection between your 123.hp.com/envy4500 printer and computer. Link the devices to the same network of a router or access point. Ensure the router provides an active internet connection. If you connect the devices using a USB cable, ensure the cord is plugged to the respective port of the printer and computer. Check the power connection to the printer. Never plug the power cable into a surge protector as it can deliver power fluctuations. If the offline issue continues, get more solutions from our technical support team by contacting them.
