how do i do a full factory reset on my hp laserjet m234dwe? need to wipe all settings.

Use the Embedded Web Server to restore factory defaults. This resets all settings, not just network.

Steps:

1. Open the Embedded Web Server (EWS) on a connected computer. Access it via the HP Smart app, HP printer software, or a web browser using the printer's IP address.
2. On the EWS, click the System tab.
3. Click Service.
4. In the 'Restore Defaults' area, click the 'Restore defaults' button.
5. The printer will automatically restart. This completes the reset.

If that didn't work: You may only have reset network settings. For a network-only reset, use the hardware buttons: Press and hold the Information button for 3 seconds (all buttons light up), then immediately press and hold the Wireless and Cancel buttons together. The printer restarts into wireless setup mode. This does not reset all other printer settings.

Heads up: Restoring factory defaults will erase any custom configurations. You will need to set up wireless printing again afterward.
