With IPHost Network Monitor you can run WMI Protocol monitoring of various devices in your network.
To create a WMI monitor for Protocol, provide host name (it must be a Windows host) and specify custom WQL query:
The Protocol property has two values: 'Raw' indicates printing directly to a device and 'Lpr' indicates printing to device or print server; LPR is a legacy protocol, which will eventually be replaced by RAW. Some printers support only LPR.
The Win32_TCPIPPrinterPort class represents a TCP//IP service access point. For example a TCP/IP printer port. Note: The SE_LOAD_DRIVER_PRIVILEGE privilege is required on this class.
IPHost Network Monitor is an advanced and easy tool for monitoring LAN and WAN networks, network servers, workstations and TCP/IP devices. Use IPHost Network Monitor to monitor your servers, domains, computers and devices.
