When printing a document in an environment where user authentication or account track is employed, you need to send the authentication information (user name and password) to this machine to execute printing. This requirement limits the users who can use this machine, preventing unauthorized use by a third party.
When this machine receives a print job from a user who is not allowed to print or a print job without authentication information, this machine automatically discards the job.
Printing starts successfully when the authentication information is judged correct.
