Look here they have a great online resource -

It tells you how to reset the card back to factory defaults this will let it pick up DHCP. What I suggest then is to then telnet into the card and use the menu commands to set it up the way it should be (static).
You can also do it by the control panel -
To configure an HP jetdirect card do this:
1. Hit the online button once and the light will go out indicating off line.
2. hit the menu button until you get TEST
3. hit the item button until you get SELF TEST
4. hit the enter button ( you will see 05 SELF TEST in the window). After about 10 seconds or so the printer will print out a page of info. In this info will be the ip address of the card. If you can, it will be easiest to telnet to this ip address and there you will find a simple menu that is very easy to use. The card can be configured from there.
You can also configure the ip address from the printer.
To configure TCP/IP from the printer:
(The star means selected or entered; without the star the choice you make is not saved; hit enter to get the star and save your choice)
1. Hit the offline button
2. Hit the menu button until you see AUX IO MENU
3. Hit the item button until you see CFG NETWORK = NO
4. Hit the + button to get CFG NETWORK = YES
5. Hit the enter button to get CFG NETWORK = YES *(this saves your choice)
6. Hit the item button to get CFG TCP/IP = NO
7. Hit the + button to get CFG TCP/IP = YES
8. Hit the enter button to get CFG TCP/IP = YES *(this saves your choice)
9. Hit the item button to get IP BYTE 1 = 0 (This could be any number between 0 and 255, hitting plus increases the number in steps of 1 hold the plus button down to automatically advance the numbers. Hold down the shift button red letters to make numbers go backwards this is where you set the ip address of the printer. This number will be the first number in your address like this: If your IP is 192.168.1.1, this will be the 192 part. Before you hit the the item button again to get to IP BYTE 2 = 0 (or what ever number it is set to) be sure you have hit enter to change the entry and save it.
10. Hit the item button to get IP BYTE 2 = 0
11. Hit the item button to get IP BYTE 3 = 0
12. Hit the itme button to get IP BYTE 4 = 0
13. As you continue to hit the item button you will get something like this SM BYTE = or LS BYTE = or GW BYTE = these stand for Subnet Mask, GateWay, SysLoGserver. You may want to set these too. Again, be sure to hit enter to get the * which means you have saved the value. You can always test your entry procedure by using the test menu above that will tell you if you successfully changed the ip address, subnet mask, and defalult gateway.
