Problem
When sending one print job to the Print Server from the Print dialog, then it shows error 401, and the print job is not sent to the printing queue.
Solution
Print Server Security token mismatch with neoCatalog Print Server management. The connected Print Server uses one different security token that is not configured in neoCatalog Print server settings.
Go to the Print Server management in neoCatalog administration and paste the copied security token from the Print Server configuration.
