ENWW TCP/IP Configuration 34
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.
TCP/IP Configuration Tools
Depending on your printer and operating system, an HP Jetdirect 
print server can be configured with valid TCP/IP parameters for 
your network in the following ways:
● Using Software. You can use your printer installation 
software on supported systems. For more information see 
Chapter 2
, “HP Software Solutions Summary”.
● BOOTP/TFTP. You can download the data from a 
network-based server using BOOTP (Bootstrap Protocol) and 
TFTP (Trivial File Transfer Protocol) each time the printer is 
turned on. For more information, see “Using BOOTP/TFTP
”.
The BOOTP daemon, bootpd, must be running on a BOOTP 
server that is accessible by the printer. 
● DHCP/TFTP. You can use Dynamic Host Configuration 
Protocol (DHCP) and TFTP (Trivial File Transfer Protocol) each 
time the printer is turned on. These protocols are supported on 
HP-UX, Solaris, Red Hat Linux, SuSE Linux, Windows 
NT/2000/Server 2003, NetWare and Mac OS systems. (Refer to 
your network operating system manuals to verify that your 
server operating system supports DHCP.) For more 
information, see “Using DHCP
”.
