Available Network Services
This section lists the well-known ports of HP Jetdirect services being accessed. A remote port is associated with a remote client application. A local port identifies a service and port number on the HP Jetdirect print server. A port is either secure or not secure, depending on the IPsec policy configuration.
For example, for LPD printing enabled with an IPsec rule, a local TCP, secure, port 515 might be listed. Port 515 is a well-known port for LPD services. If the print server is connected to a remote application’s port 25, it might list remote TCP, unsecure, port 25 of the client.
