Printing - Clear Credentials From macOS Keychain

If you attempt to submit a print job from your Mac and the Print Center shows the status of the document is "Hold for Authentication", there is a authentication issue between your device and the print server that is preventing the document from spooling.

Follow the steps in this article to resolve the communication issue.

1. Open the Keychain Access application on your Mac by searching for it using Spotlight
   
2. Authenticate using your Mac account password to unlock the keychain
   
3. In the Keychain Access application, click on the login keychain under the Default Keychains section of the sidebar. Then search for "print" in the search bar. You should see a result populated similar to what is pictured in the screenshot below. Note that there might be multiple results- you can safely delete all matches, but understand that the result of doing so is that you will need to enter your NetID password again when you attempt to print
   
4. Attempt to re-submit your print job to the printer. This time you should be prompted to authenticate with your NetID and NetID password. Note that you need to prepend "AD\" in the username field. To save the new credentials in your Mac's keychain check the box. This will cause the printing subsystem to use the saved credentials on subsequent print jobs and you will not be prompted again.
   
5. After successfully authenticating, your print job will now spool as desired
