ENWW TCP/IP Configuration 41
DHCP Requests Enable/Disable
When a default IP address is assigned, you can choose to send, or 
not send, periodic DHCP requests. DHCP requests are used to 
retrieve IP configuration settings from a DHCP server on the 
network. By default, this parameter is enabled, allowing DHCP 
requests to be transmitted. However, this parameter may be 
disabled through supported configuration tools such as Telnet, a 
Web browser, and SNMP management applications.
HP Jetdirect Wireless Print Server. When initially powered 
on, a factory-default wireless print server that has no connection to 
a network will likely self-assign a link-local IP address. If a network 
connection to a DHCP server-based network is made, the IP address 
will likely be reconfigured because DHCP requests on the print 
server are enabled by default.
Default IP on Wireless and Wired Print Servers
Wired and wireless print servers may have different default IP 
configuration results:
● When powered on, a factory-default wired print server will 
systematically use BOOTP, DHCP, and RARP to retrieve its IP 
settings. Up to two minutes are used. If configuration is not 
successful, a default IP address will be assigned as described 
previously.
● For a factory-default wireless print server, a network connection 
must first be configured before it can communicate on a network. 
Therefore, retrieval of IP settings from a network is limited to 
about four seconds. During this time, a single BOOTP request 
is transmitted, and broadcast packets are sensed. Because a 
response from a BOOTP server on an Ad Hoc network is 
unlikely, and the number of broadcast packets sensed will be 
minimal, a default IP configuration using link-local addressing 
is likely.
However, the IP configuration may change once the wireless 
print server is connected a DHCP network because the sending 
of DHCP requests will be enabled by default. 
Configuration tools that require a specific default IP address to 
initially communicate with a factory-default print server may not 
work without modification. For the default IP address settings on 
the print server, see the Jetdirect configuration page.
