Welcome to the HP Support Community. I'd be happy to assist you with the  "How to connect the printer to network".


Try the steps below to connect the printer to a network-


Connecting the printer to a wireless network with WPS


Complete the network connection by putting the printer and the router in WPS setup mode. Once connected, install the HP software to wirelessly connect the printer to your computer or mobile device.


Your network must use Wi-Fi Protected Access (WPA or WPA2) security, and your router must support WPS. Google, eero, Luma, and Plume are some router brands that might not support WPS.

  1. Make sure your router has a WPS button or a button with the WPS icon 


  1. Place the printer within the range of the Wi-Fi router signal.
  2. Put the printer in WPS connection mode.
    • Printers without a touchscreen control panel: Press and hold the Wireless button for five seconds until the wireless light flashes. 
  1. Within two minutes, press and hold the WPS button on the router for three to five seconds, or until the connection process begins.
  1. Return to the printer and check the status of the wireless light or bar.
    • If the light or blue bar stops flashing, the printer successfully connected to the network. Continue to the next step.
    • If the light is still flashing or turned off, continue to the frequently asked questions in this document. connection failed. Move the printer closer to the router, 
  2. Make sure your computer or mobile device is on the same local wireless network you connected the printer to.

Hope this helps! Keep me posted.
