How to Connect HP Envy 4500 Printer to WiFi?

My printer disconnected from the wifi network when we have installed the new wifi router. I don’t know how can I connect my HP Envy 4500 printer to wifi. I have tried to connect it through the wireless setup wizard but every time it fails to connect. Please help me to do the wifi set up quickly.

Hello there. It is very easy to connect your printer to wifi with the help of an application named HP Smart. Please download and install this app and then run it. Next, you need to open the app and select your printer from the list (make sure your printer is turned ON). Now right on it and click on the wireless setup option and then select your network and type your network password. Please follow the complete guide on how to connect HP Envy 4500 printer to wifi.
