Printer will not connect to wifi during setup.

We could not fully consult the manufacturer's support page for this model; the steps are general and may differ in details.

Most likely causes

usually this

Wrong wifi name or password

  • Check the wifi name on your phone or router and re-enter the password in the HP Smart app.
  • Watch for capital letters and special characters when typing the password.
  • Move the printer closer to the router while connecting.
usually this

Printer is trying the 5 GHz network but needs 2.4 GHz

  • Open your router settings or wifi app and check if you have both 2.4 GHz and 5 GHz networks.
  • Temporarily disable 5 GHz or give the 2.4 GHz network a different name so you can select it in the app.
  • Try connecting again in the HP Smart app and choose the 2.4 GHz network.
common

Phone is using mobile data or restricted network mode

  • Turn off mobile data so your phone uses wifi only during setup.
  • Ensure your phone is connected to the same wifi network you want the printer on.
  • Restart the HP Smart app and try again.
common

Temporary fault or weak wifi signal

  • Restart both the printer and the router by turning them off for 10 seconds and on again.
  • Place the printer closer to the router and try again.
  • Check other devices to confirm the wifi network is working.

Factory reset

Warning: a factory reset will erase the printer's wifi settings and any local configuration.

  1. Turn the printer on.
  2. Find the reset method for your printer; for many DeskJet models this is a specific button or a combination of buttons on the control panel.
  3. Press and hold the indicated button(s) for about 10–20 seconds until lights blink or the printer restarts.
  4. Release and wait for the printer to finish starting, then set it up again in HP Smart.

Frequently asked

Why does the app ask for location access?

HP Smart asks for location to discover nearby wifi networks; allowing it lets the app find the printer during setup.

Does the DeskJet 2720e support 2.4 GHz and 5 GHz?

These printers usually work best on 2.4 GHz; if you have both bands, choose the 2.4 GHz network during setup.

Can I pair the printer via Bluetooth?

The DeskJet 2720e mainly uses wifi for wireless printing; Bluetooth is not typically used for setup in HP Smart.

What if I see an ink or paper error?

Check that cartridges are seated correctly and there is paper in the tray, then follow any error instructions shown in the app.
