Verifying communication over the network
If the HP Jetdirect configuration page shows an IP address for the digital sender, use this procedure to
verify that the digital sender is communicating with other devices on the network.
To verify communication over the network
1. On a computer open a command prompt. Click Start, click Run, and then type cmd. An MS-DOS
command prompt opens.
2. Type ping followed by the IP address. For example, type ping XXX.XXX.XXX.XXX where
"XXX.XXX.XXX.XXX" is the IP address that appears on the HP Jetdirect configuration page. If the
digital sender is communicating over the network, the response is a list of replies from the digital
sender.
3. Verify that the IP address is not a duplicate address on the network by using the address resolution
protocol (arp -a) command. At the prompt, type arp -a. Find the IP address in the list and compare
its physical address to the hardware address that is listed on the HP Jetdirect configuration screen
in the section called HP Jetdirect Configuration. If the addresses match, all network
communications are valid.
4. If you cannot verify that the digital sender is communicating over the network, contact the network
administrator.
