User Controls
Your administrator may have established a list of authorized
users for printing. Only these users will be allowed to print. If this
feature is not in use and thus there are no authorized users, then
the printer will allow any user to print as it does prior to the
addition of the AirPrint User Control feature. Further, the
printer’s admin website will allow the admin to enable/disable the
User Control feature.
