Install Network Printer On Windows Server 2008
The normal behavior for HP printer software is that it discovers (and rediscovers) printers on the network using Web Services Discovery, which sends multicast UDP packets. In the enterprise release, the software uses only unicast UDP or TCP packets to try to relocate the printer after it has been installed. This enables the software to function properly on a network where multicast is disabled. This also results in the software being unable to find and use the printer if the IP address changes and the printer’s hostname does not resolve the IP address.Multicast rediscovery can be re-enabled in the software by changing the config.ini file that installs to C:Program FilesHPModel Nameconfig.ini. This file contains a section similar to the following. The process described in the section to install a network printer is the same process used to install a printer on a different subnet than the computer on which it is being installed.
Follow those instructions to install such a printer. However, since the printer is installed on a different subnet than the computer, the client computer cannot rediscover the printer if the IP address or hostname of the printer changes. The section below describes how to update the client computer if the IP or hostname of the printer is changed. When searching for a list of printers, WSD initiates a multicast (UDP) probe to IP 239.255.255.250 at port 3702. After the printer is installed and before every printer operation (for example, print, scan, or fax), HP checks to see if communication can be established. HP calls this action 'rediscovery.'

To do the rediscovery, WSD sends a multicast UDP packet to resolve the IP address of the printer.When searching for a printer using the IP address, WSD creates a TCP socket over port 80. This is usually done under specific circumstances. If you are installing the software via the command line and you provide an IP address to the command line, HP uses the IP address to find your printer.
However, for rediscovery purposes, HP attempts a unicast UDP probe or a TCP connection (to port 80). Subtitling for the media a handbook of an art pdf catalog online. Your firewall software might block this type of activity. If so, create a rule for HPNetworkCommunicator.exe to establish communication.If you are installing via the graphical user interface and your printer cannot be discoveredthrough the multicast probe method, you have the option to install the printer by providing the IP address. If you get the option of installing by IP, either your firewall is blocking the traffic, or your network does not support multicasting. From the software's perspective, it is the same. If it is a firewall issue, and your printer is on the same subnet as the computer, HP recommends creating rules in your firewall software to allow for multicast probes from HPNetworkCommunicator.exe.
