PortName (128 bytes): A null-terminated Unicode string, which is the name of the port.

Version (4 bytes): A 32-bit unsigned integer that specifies the version number of the PORT_DATA_2 structure. This value MUST be 0x00000002.

Protocol (4 bytes): A 32-bit unsigned integer that specifies the protocol to use for the port. This value MUST be either PROTOCOL_RAWTCP_TYPE (0x00000001), indicating that the port expects RAW print data, or PROTOCOL_LPR_TYPE (0x00000002), indicating that the port expects to be driven as an LPR port.

Name/value	Description
PROTOCOL_RAWTCP_TYPE 0x00000001	The port expects RAW print data.
PROTOCOL_LPR_TYPE 0x00000002	The port expects to be driven as an LPR port.

Size (4 bytes): A 32-bit unsigned integer that specifies the size, in bytes, of the PORT_DATA_2 structure.

Reserved (4 bytes): A 32-bit unsigned integer that is set to zero.

HostAddress (256 bytes): A null-terminated Unicode string, which is the IP address or host name of the printer.

SNMPCommunity (66 bytes): A null-terminated Unicode string, which is the Simple Network Management Protocol (SNMP) [RFC1157] community name of the printer.

PaddingForAlignment (2 bytes): 2 bytes of padding to align the DoubleSpool field on a 4-byte boundary. The contents of this field MUST be ignored.

DoubleSpool (4 bytes): A 32-bit unsigned integer that, if nonzero, indicates double spooling is enabled or, if zero, indicates that double spooling is disabled.

Queue (66 bytes): A null-terminated Unicode string, which is the LPR queue name.

DeviceType (514 bytes): A null-terminated Unicode string, which is the generic SNMP system device description OID 1.3.6.1.2.1.1.1 (for a network device object ID).

PortNumber (4 bytes): A 32-bit unsigned integer that is the port number of the device.

SNMPEnabled (4 bytes): A 32-bit unsigned integer that, if nonzero, indicates that the device supports SNMP.

SNMPDevIndex (4 bytes): A 32-bit unsigned integer that is the SNMP device index.

PortMonitorMibIndex (4 bytes): A 32-bit unsigned integer that specifies the index in the network devices Printer Working Group (PWG) [IEEE-PWG] port Monitor Management Information Base (MIB) for the current TCPMON port. This index is used to query the IEEE 1284 device ID for the attached printer. For details, see [IEEE1284].
