Make sure your Android device, printer, and network are working correctly and ready for printing.
-
Confirm your Android device is connected to the network: On your Android device, open the Wi-Fi settings and make sure your device is connected to the network you want to connect the printer to.
-
Confirm that the printer is on and connected to the network: The printer might be in sleep mode, power saving mode, or turned off. Touch or press a button on the printer control panel to wake the printer. To confirm your printer connection, select your connection type.
-
Wireless network connection: On the printer, make sure the light next to the Wireless icon

is either on and steady, or blinking. If the wireless light is not on or blinking, press the Wireless button, or open the Wireless network or Settings menu to make sure the wireless signal is turned on.
-
Wired network connection: Check that the cable is connected to the printer Ethernet port

and to an available port on the router. The green link light should be steady, and the orange activity light should blink when the cable is connected.

-
Make sure the app you are trying to print from supports the option to print. Look for a
Print icon

to confirm the app supports printing.
-
Move the printer and router closer together: Move the printer and your Android device closer to your wireless router, but no closer than 6 ft (1.8 m). Wireless signals can be weaker at greater distances between the printer and the router.
-
Check the router band: Many routers can operate in both 2.4 GHz and 5.0 GHz frequency bands, but not all HP printers support both bands. Make sure the 2.4 GHz router band is enabled and broadcasting. If the router broadcasts separate network names (SSIDs) for each band, connect the printer to the 2.4 GHz band SSID.
If the issue persists, continue to the next step.
