HP Web Jetadmin - Ports

Ports

HP Web Jetadmin listens continuously on several ports and opens other ports for specific functionality. The following table lists the ports that HP Web Jetadmin uses.
note:
HP Web Jetadmin uses Internet Control Message Protocol (ICMP) in the discovery process. HP Web Jetadmin sends an ICMP echo request to determine if the IP is active.
Port number
Type
Inbound (I) or Outbound (O)1
Description
69
UDP
I
TFTP Incoming Port: HP Web Jetadmin uses this port as a staging area for firmware images during HP Jetdirect firmware updates. Through SNMP, HP Web Jetadmin triggers HP Jetdirect to retrieve firmware through this port.
80
TCP
O
HP Web Jetadmin uses this port to qualify the link to the HP Embedded Web Server on the device and to retrieve the firmware images from the web.
161
UDP
O
SNMP: HP Web Jetadmin and other management applications use SNMP to communicate with and manage devices. HP Web Jetadmin uses this port on the printer to issue Set and Get commands to the SNMP agent.
427
UDP
I
SLP Listen: HP Jetdirect-connected devices use Service Location Protocol (SLP) to advertise their existence. When the passive SLP discovery feature is enabled on HP Web Jetadmin, devices send multicast packets to this port on the HP Web Jetadmin server.
443
TCP
O
HTTPS: The HP Web Jetadmin service and HPWSProAdapter service send device configurations and queries to this port over HTTPS.
HPWSProAdapter uses this port to communicate with devices that do not support Web Services and are configured to redirect all of the network traffic to HTTPS.
843
TCP
O
HP Web Jetadmin uses this port to configure some settings, such as fax and digital sending, on some HP MFP device models.
1433
UDP
O
Microsoft SQL Server: By default, HP Web Jetadmin installs the SQL Server database on the same host. Optionally, you can configure HP Web Jetadmin to communicate with a SQL Server database on a different host. HP Web Jetadmin uses this port to facilitate communication with a remote SQL Server database.
2493
UDP
I/O
Build Monitor: This is an HP Web Jetadmin server port that is kept open. Other HP Web Jetadmin servers use this port to discover running instances of HP Web Jetadmin.
3329
TCP
I
HP Web Jetadmin uses this port to receive device announcements from HP JetAdvantage Security Manager. For more information about configuring HP JetAdvantage Security Manager to forward device announcements, see the HP JetAdvantage Security Manager documentation. For more information about configuring HP Web Jetadmin to receive forwarded device announcements, see the online Help for the Instant on Listen feature.
37022
UDP
O
WS Discovery: HP Web Jetadmin uses this port to perform a Web Services discovery on newer HP devices.
39102, 3911
TCP
O
WS Discovery: HP Web Jetadmin uses this port to retrieve details about the device Web Services during a discovery. HP Web Jetadmin uses these details to establish the WS communication paths that it needs to manage devices.
HP Web Jetadmin uses port 3910 to retrieve print requests and uses port 3911 to retrieve the printer status.
4088
TCP
I
Remoting: HP Web Jetadmin uses this port as the primary communication channel between a started HP Web Jetadmin client and its corresponding HP Web Jetadmin server.
4089
TCP
I
Client Event Notification: HP Web Jetadmin uses this port to communicate change events from the HP Web Jetadmin server to the client. These events trigger the client to pull updates from the server through the Remoting interface. In previous releases of HP Web Jetadmin, Windows assigned this port.
76272
TCP
O
Web Services (HTTPS): HP Web Jetadmin uses this port to communicate with HP FutureSmart devices and older laser devices for some operations, such as OXPd.
For devices that do not support Web Services, the HPWSProAdapter Service acts as a gateway between HP Web Jetadmin and the devices. The HPWSProAdapter Service receives Web Services requests from HP Web Jetadmin, and then sends the translated requests to the devices over port 8080 (an unsecure connection, an HP Embedded Web Server password is not configured on the devices) or port 443 (a secure connection, an HP Embedded Web Server password is configured on the devices).
8000
UDP
O
HP Web Jetadmin Discovery Listen: HP Web Jetadmin uses this port on remote IP hosts to detect earlier versions of the HP Web Jetadmin software.
8000
TCP
I
Web Server: HP Web Jetadmin provides an HTTP listener for the initial client launch and online Help content.
8050
TCP
I
Device Eventing Callback (HTTPS): Newer HP devices use a WS eventing protocol for management communications.
8080
TCP
O
HPWSProAdapter: HPWSProAdapter uses this port to communicate with devices that do not support Web Services and are not configured to redirect all of the network traffic to HTTPS. HP Web Jetadmin sends device configurations and queries to this port.
8140
TCP
I
OXPm Web Services (HTTP): This is the communication port for HP Open Extensibility Platform (management operations).
8143
TCP
I
OXPm Web Services (HTTPS): This is a secure communication port for HP Open Extensibility Platform (management operations).
8443
TCP
I
Secure Web Server (HTTPS): HP Web Jetadmin provides a secure HTTPS listener for the initial client launch, Help content, and device file transfer operations.
9100
TCP
O
Printer Firmware Upgrade and Test File Operation: HP Web Jetadmin uses this printer port to transfer printer firmware files, test job files, and PJL configuration files.
27892
UDP
I
Traps Listener: HP Web Jetadmin uses this port for SNMP-based alerts and for By User Data Collections.
27893
UDP
I
WS Hello Listener: HP Web Jetadmin monitors this port for incoming WS Hello packets from the HP WS Pro Proxy Agent software that is installed on hosts in the enterprise. When HP Web Jetadmin detects a packet, it follows up to determine whether there are any printers to discover on the sending host. For more information, see the HP Web Jetadmin 10.4 Proxy Agents Readme. This document is available from the HP Web Jetadmin support page (in English).
59113
TCP
O
Microsoft SQL Server: By default, HP Web Jetadmin installs the SQL Server database on the same host. Optionally, you can configure HP Web Jetadmin to communicate with a SQL Server database on a different host. HP Web Jetadmin uses this port to facilitate communication with a remote SQL Server database.
1The I/O column represents the communication direction with respect to the HP Web Jetadmin server host. HP Web Jetadmin uses random source ports when communicating with ports on remote IP addresses.
2HP Web Jetadmin uses ports 7627, 3702, and 3910 internally to communicate with devices. To ensure proper communication, these ports must be kept open for communication directly with the device and with the internal HPWSProAdapter service.
When using WMI discovery (discovering PC-connected printers without an HP proxy installed on the PC), several ports have to be opened for the WMI communication (DCOM ports, WMI ports, and WMI connection applications (UnsecApp or WMI_OUT)). For more information, see: https://msdn.microsoft.com/en-us/library/aa822854.aspx
Open the ports in the Windows firewall by using a batch file
HP Web Jetadmin opens the ports listed in the table to communicate with devices. However, the firewall that you are using might block the connection and prevent HP Web Jetadmin from communicating with the network.
Instead of adding firewall rules for these ports one at a time, you can create a batch file that opens all of the ports that HP Web Jetadmin requires for the Windows firewall at one time. For instructions, see the Create a Batch File to Open HP Web Jetadmin Required Ports in the Windows Firewall white paper. This white paper is available from the HP Web Jetadmin support page.
