Hi @foxybrown

Welcome to the HP Support Community.

Thank you for posting your query.

I understand that you would like to reset the password for the printer. In order to reset it or perform a factory reset, here are some general methods that work for many HP models. The exact steps can vary depending on the model, but these are commonly effective:
 

Method 1: Use the Printer Control Panel (Touchscreen Models)

1. Go to the Home screen on the printer.
2. Tap the Setup or Settings icon (gear symbol).
3. Navigate to Printer Maintenance or Tools.
4. Select Restore or Restore Defaults.
5. Choose Restore Factory Defaults and confirm.

This will reset all settings, including the admin password and Wi-Fi configuration 

Method 2: Button Combination for Non-Touchscreen Models

1. Turn off the printer.
2. Press and hold the Cancel button.
3. While holding Cancel, press and hold the Power button.
4. Continue holding both for about 10–15 seconds until the printer powers on and shows signs of resetting.

This method works on many HP DeskJet and LaserJet models 

Method 3: Use the HP App or Embedded Web Server (EWS)

1. Open the HP App on your computer or phone.
2. Go to Advanced Settings to open the Embedded Web Server.
3. Navigate to Settings > Restore Defaults.
4. If prompted for a password, try:
   • Username: admin
   • Password: admin or the PIN found on a sticker inside the printer (usually near the cartridges).

If you can access the EWS, this is the most reliable way to reset the printer.

Take care and have an amazing day!
