b. Mac: Click Applications, click Utilities, and then open the Terminal application. The terminal window 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 is shown on the HP Jetdirect configuration page. If the MFP is communicating over the network, the response is a list of replies from the MFP. 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 page in the section called HP Jetdirect Configuration. If the addresses match, all network communications are valid. 4. If you cannot verify that the MFP is communicating over the network, contact the network administrator.
