Only in the case that the Jetdirect card is used: configuration through this protocol cannot be used. Rarely used. Some HP software utilities may perform web service requests to this port to retrieve device status information. If disabled, the printer EWS would not be reachable, and HP Web Jetadmin and other utilities might not work. Access to the Automatic Firmware Upgrade host (under hp.com), performing connectivity tests. If disabled, the printer will not be able to automatically receive the latest FW upgrades and the connectivity test will always fail. Used by HP Large Format devices for Kerberos authentication. Scan to network folder (to SMB destination). If disabled, MFPs will not be able to send scanned data to networks folders. This port can be accessed by any SNMP Management utility. HP Web Jetadmin use SNMP to configure and query the status of a printer. This port can be used when the network is configured to capture trap information. Many SNMP Management utilities can be configured to capture traps.
