HP OFFICEJET PRO 8710 not working with MAC OS 11

[UShelp]

I cannot print after I've installed MAC OS 11 when using a HP OfficeJet Pro 8710. I also receive an error message - HPSmart wants to use your confidential information stored in "HP Smart-HPConnected-LastUserName" in your keychain.

Hi @Rosey75,

I'd like to help!

Try updating mac and printer firmware

To update the printer's firmware, refer - HP Printers - Updating or Upgrading Printer Firmware 

 To update Mac, try these steps - How to update the software on your Mac

Try the below suggestions -

1. Uninstall HP Smart  
2. Re-Install the HP Smart 

• Download HP Easy Start and follow the on-screen to complete the installation.

You may also add the AirPrint printer to the Mac printer queue

Confirm you are using AirPrint by adding the printer in System Preferences.

1. Click the Apple menu, click System Preferences, and then click Print & Scan or Printers & Scanners.

   Figure : Example of the Printers & Scanners window

   

2. Check if your printer name displays in the Printers list, and then do one of the following steps.

   • If your printer is listed, remove and re-add the printer to confirm it is set up for AirPrint. Click the printer name, click the minus sign  to delete the printer, click the plus sign , click Add Printer or Scanner, click the printer name and then continue to the next step.

   • If your printer is not listed, click the plus sign, click Add Printer or Scanner, click the name of your printer, and then continue to the next step.

   • If your printer is not listed in the Add Printer or Scanner window, go to the Frequently asked questions in this document to resolve connection issues, try to add the printer again, and then continue to the next step.

3. Confirm AirPrint or Secure AirPrint displays in the Use or Print Using menu, and then click Add.

   Figure : AirPrint displays in the Use menu

   

4. Open a document or photo, click File, and then click Print.

Hope this helps! Keep me posted.

Hi,

The keychain is a utility that is part of macOS that stores the passwords on your computer. The password should be the admin or login password for your computer. Please contact Apple directly if you need further assistance. The keychain is not supported by HP.
