To **change the password on an HP printer**, you typically use either the **HP Smart app** or the printer’s **Embedded Web Server (EWS)** by accessing its IP address from a web browser.

The common methods are:

1. **Using the HP Smart App** (for supported models):
– Switch on your printer and pair it with the HP Smart app on your smartphone (Android or iPhone).
– Open the app and select your printer.
– Navigate to **Advanced Settings > Security > Password Settings** or **Change Administrator Password**.
– Enter the current or default password (often “admin” with no password initially), then set and confirm your new password. This process is demonstrated in detail in tutorial videos and the HP Smart app interface[1][2][3].

2. **Using the Embedded Web Server (EWS):**
– Find your printer’s IP address by printing a network configuration page or checking your printer’s display menu.
– Enter the IP address into a web browser on your computer connected to the same network.
– Log in with the admin username (usually “admin”) and the current password (default might be blank).
– Go to the **Security** or **Administrator Settings** section.
– Change the password, confirm it, and save the changes[2][5].

3. **Changing WiFi Direct Password:**
– Similar steps apply if you want to change the WiFi Direct password: access the printer’s IP via a browser, go to **Network > WiFi Direct**, then **Edit Settings**, set the connection method to “Manual,” and change the password[4][5].

If the admin password was never changed, the default username is typically *admin* and often the password field is blank or set to a default password printed on a sticker on the printer (check the back or inside the printer)[3].

If you forget the password, you may need to reset the printer to factory defaults or use recovery methods specific to your model[2].

This approach works for most HP DeskJet, LaserJet, and OfficeJet printers with a network interface[1][2][3][5].
