You can set the printer to require a user code when someone tries to use the printing function.
When print jobs are restricted, you can only authenticate through the PCL6 printer driver. Printing from the PostScript 3 printer driver will not be possible.
Using Web Image Monitor, enable user restriction for the printing function, and then register users who can use the function.
For each user, you can specify if the printing function is available upon authentication. A maximum of 30 users can be registered.
For details about configuring the user restriction settings, see Restricting Printing Function According to User.
