Restricting use of the LPD protocol to submit jobs

You can limit the hosts that can use the LPD protocol to submit jobs to all the input devices with the same parent server. The default is to allow input from all systems.
To restrict the use of the LPD protocol:
  1. Click the Administration tab.
  2. In the left pane, click Settings ⇒ System.
  3. In the Hosts allowed to submit LPD jobs field, type a list of authorized host names or IP addresses separated with semicolons.

    You can use an asterisk (*) to represent zero or more characters. Values that contain only digits (0–9), decimal points (.), and asterisks (*) are compared to the IP address of the incoming connection. Values that contain one or more alphabetic characters (A–Z, a-z) are compared to the host name of the incoming connection.

    A list value of * means that all hosts are allowed to submit jobs. An empty list value means that no hosts are allowed to submit jobs.

  4. Click SAVE.
