@Mike1460, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 

If your HP printer is showing a "WPA passphrase doesn’t match exactly" error even though you're sure the password is correct, here are some steps to help resolve the issue:

Double-check the Wi-Fi Password

• Ensure there are no extra spaces before or after the password.
• Passwords are case-sensitive—make sure Caps Lock is off/on as needed.

Restart Devices

• Restart your printer, router, and computer or mobile device.
• Sometimes a simple reboot clears up temporary glitches.

Reconnect Using the Printer’s Control Panel

• Go to Setup > Network Setup > Wireless Setup Wizard.
• Select your Wi-Fi network and re-enter the password carefully.

Forget and Reconnect to Network

• On the printer, go to Network Settings > Restore Network Defaults.
• Then try reconnecting using the Wireless Setup Wizard again.

Check Router Settings

• Ensure your router is using WPA2 or WPA3 encryption (not WEP).
• If your router has MAC address filtering, make sure the printer is allowed.
• Try changing the Wi-Fi channel or SSID temporarily to test.

Update Printer Firmware

• If possible, connect the printer via USB and check for firmware updates using the HP Smart app or HP Support Assistant.

Use HP Smart App for Setup

• Download the HP Smart app on your phone or PC.
• Use it to set up the printer—it often handles Wi-Fi setup more reliably.

I hope this helps. 

Take care and have a good day.
