Welcome to HP Forums, 
This is a great place to get support, find answers and tips. Thank you for posting your query. I'll be more than glad to help you out 🙂 

If you are able to print using the USB connection, change from a USB to a Wireless Connection.

For instruction, refer to: Changing from a USB to a Wireless Connection  

If issue persists, reset network settings and connect the printer using the wireless setup wizard from the printer front panel.

1. From the home screen of your printer control panel, touch the Wireless icon .

2. Touch the Setup icon .

3. Touch Restore Network Defaults or Restore Network Settings, and then touch Yes to confirm your selection.

4. After the default network settings are restored, touch the back arrow, touch Wireless Settings, and then touch Wireless Setup Wizard.

   The printer searches for available networks.

5. Touch the name of your wireless network.

6. If your wireless network does not display in the list of wireless networks, touch Enter New Network Name, and then type the name of your wireless network.

   NOTE: 

   Type the exact network name, including any uppercase and lowercase letters.

7. Type the WEP or WPA key (network password), and then touch Done.

   If you do not know your network password, go to Find Your Wireless WEP, WPA, WPA2 Password..

   Once the printer connects to the wireless network, the blue Wireless light on the control panel turns on solid.
