You can set the printer to require a user code when someone tries to use certain printer functions.
When print jobs are restricted, you can only authenticate through the PCL printer driver. Printing from the PostScript 3 printer driver will not be possible.
Use of the following functions can be restricted:
PictBridge printing
Printing (both color and black-and-white)
Color printing (black-and-white printing is still allowed)
To enable this setting, you must first configure the printer via Web Image Monitor.
