Usually it it set to pick up IP from DHCP/BootP.
If someone had assigned a fixed IP and it is now unknown. It is better to reset the print server to factory default by pushing the little reset button,
Then check you DHCP server for the newly assigned IP address.
You will need a version of HP Jetadmin or HP webjetadmin to configure this print server
There should be a software program that allows you to change the IP Address that came with the unit. If you don't have that, you would need to reset the unit to factory defaults (which may not be possible without the software) set the device in the same subnet as your DNS router, change the BOOTP/DHCP table with the MAC Address and new IP Address.
You can do of course, but just remember that the life of any electronic device equates to the amount of time it is on, so by leaving it on you are reducing its lifespan (maybe by only a tiny bit) and wasting energy.
If components are left on for a long time then there is a chance that they start to heat up, and heat eventually means failure for circuitry.
Get the IP address subnet and gateway address of a computer in the same network.
Usingthe LJ5's control panel, setup a static IP for the Jet Direct using thenumbers you got from the Laptop, except change the last number of theIP to one that is not being currently being used. Perhaps adding 5 or10 to the highest number in use. Here are the steps to configure the LJ5.
1.Press MENU, repeatedly, until the following message appears on thecontrol panel: HP LaserJet 5/5n/5m and the original Color LaserJet: HPMIO MENU 2. Press ITEM. CFG NETWORK=NO* will appear. 3. Press the PLUS button once. CFG NETWORK=YES* will appear. 4. Press ENTER or SELECT. 5. Press ITEM repeatedly until CFG TCP/IP=NO* appears. 6. Press the PLUS button. CFG TCP/IP=YES* will appear. 7. Press ENTER or SELECT. 8. Press ITEM until BOOTP=YES* appears. 9. Press the PLUS button. BOOTP=NO will appear. o When using BootP or DHCP, keep the setting BOOTP=YES*. o The BootP or DHCP server will configure the TCP/IP parameters on the HP Jetdirect. o No other TCP/IP configuring is necessary. 10. Press ENTER or SELECT. 11. Press ITEM. IP BYTE 1 = (value) will appear. 12.Press the PLUS button until the value of the first byte of the IPaddress appears on the control-panel display. By pressing SHIFT and thePLUS button, the value will decrease. 13. Press ENTER or SELECT. 14. Press ITEM to continue. Repeat Steps 11-13 to configure the remaining bytes of the IP address. 15.Repeat Steps 11-13 to configure the subnet mask bytes (SM BYTE 1=),syslog server IP address (LG BYTE 1=), default gateway (GW BYTE 1=),and timeout (TIMEOUT=). 16. Press ONLINE. Print a self-test page to verify the IP settings. 17. If the test page does not show the correct settings, power cycle the printer and reprint the test page.

Assuming the JetDirect card is installed and properly functioning, use the following. Also, you may have to update the rom on the I/O Card to the latest version.
From the front control panel message, Ready or Ready to Plot, press ENTER.
Press the Up arrow key until I/O Setup appears, and then press ENTER.
Press the Up arrow key until Modular appears, and then press ENTER.
From the front control panel message, Cfg Network=No, press ENTER.
Press the Up arrow key to change to Yes, and then press ENTER.
Using the Arrow keys, scroll to Cfg TCP/IP=No appears, and then press ENTER.
Scroll to Yes, and press ENTER.
Press the Up arrow key until BootP=Yes appears, and press ENTER.
Press the Up arrow key to change to No. Press ENTER (When using BootP or DHCP, keep the setting BOOTP = YES *. The BootP or DHCP server will configure the TCP/IP parameters on the HP Jetdirect. No other TCP/IP configuring is necessary.
Press the UP arrow once to get to the IP byte section.
To change the IP byte, proceed as follows:
Press the Up or Down arrow key to change the number.
Press the Up key to continue to IP Byte2=xxx.
Configure the remaining bytes of the IP address in the same manner. A valid IP address is required for proper operation.
Configure the subnet mask bytes (SM), syslog server IP address (LG), default gateway (GW), and timeout (TIMEOUT) by pressing the ENTER and the Up or Down arrows in the same manner as above. The timeout parameter default is 90 seconds. Up to 3,600 seconds can be configured. If set to zero, the timeout feature of the HP Jetdirect print server is disabled; TCP/IP connections will remain open until closed by the server.
Press PREVIOUS repeatedly, until the Ready to Plot or Ready message appears. Refer to the HP Jetdirect Network Interface Configuration Guide to configure the network operating system.
Press the Up and Down arrow keys simultaneously to save the IP address on a 750/755 plotter. (A page should print and the IP addresses will be saved.)
You can reset the MarkNet X2000 to factory defaults - which includes resetting the IP address to 0.0.0.0 like this: 1. Press and hold the Test button until all four lights stay lit simultaneously, then release the Test button. 2. When #3 and #4 lights light simultaneously, press and release #1 (the Menu button). 3. When #3 lights press and release #1 (the Menu button).
4. At this point the X2000 print server has been restored to the
factory default settings and should have an IP address of 0.0.0.0.
How this works:
Restoring the PocketPrintServer to Factory Defaults
In most cases, the best way to restore the PocketPrintServer to
factory defaults is through "telnet". However, if you are unable to
connect to the device because of a configuration error, use the
following method which does not require a network connection.
To restore the PocketPrintServer to factory defaults, complete
the following steps:
1. Disconnect the PocketPrintServer from the network and
power cycle it. When it powers up, the LED will rapidly
blink orange for five seconds.
2. Power down the device during the rapid orange blink
period. Power up the device and power it down during
that orange blink period two more times.
3. Reconnect the network cable and power up the
PocketPrintServer. It will have restored itself to factory
defaults and will rapidly blink green as it searches for a
RARP or BOOTP server to find an IP address.
If an IP address has not been permanently assigned when the
PocketPrintServer is powered on or reset, it will look for a "ping"
packet on the network. If the PocketPrintServer receives a "ping"
packet within two minutes, it will accept the IP address in the
"ping" packet as its own address.
To use Gleaning, you must have super-user privileges on a UNIX
system. Gleaning also works under Windows 95 and Windows NT.
1. Add an entry in the ARP table that assigns an IP address to the
Ethernet address of the PocketPrintServer. To do this, use the
arp -s temp
arp -s 192.168.42.24 00:02:16:00:00:01 temp
2. Start a continuous "ping" to the PocketPrintServer.
Example: ping 192.168.42.24
On some systems, this may require an additional parameter.
Some implementations of "ping" only send out one "ping"
packet which could get lost in transit. Check your system
documentation for more information.
3. Connect power to the PocketPrintServer.
The PocketPrintServer will "glean" its IP address from the "ping"
packet. This IP address will remain in effect until the
PocketPrintServer is power cycled or reset. Therefore, a permanent
IP address should be assigned by running the ExtendView TCP/IP
utility or via "telnet".
