This specific error will only occur on Macintosh computers and is indicating either a wrong username or password. This typically happens either on first setup or when someone changes their password.
Fix:
1) Click on the Refresh button to the right of the error. The box below will appear.
2) Confirm that "Name:" is their Bethel Username
3) Change the "Password:" to the correct Bethel password (same one that gets used for MyBethel)
After changing to the correct username/password combo the print job should leave the print queue.
