Troubleshooting Printing

Hold for Authentication Error

This error typically indicates the password associated with the username is not correct. If a password was mistyped on entry or if an old password exists in your keychain, you will receive this error.

Update Keychain

Keychain entries are saved username/password combinations. They are associated with a specific login type. When you Remember my credentials when printing, this creates a keychain entry associated with WPI Printers.

Unfortunately, not all keychain entries are the same, so we recommend:

  1. Open Keychain or Keychain Access
  2. Under the Keychains, choose "login"
  3. Under the Category, choose "passwords"
  4. Scroll through the entries searching for:
    • queuename
  5. Once found, right click (or two-finger click) and choose Delete

This will allow you to re-enter your credentials when you go to print.
