Or, you attach the printer directly to the server via parallel port (RS-232) cable. Or upgrade the server with an USB port, and connect it that way. gl

Hi,
There is not wireless netwrok card is HP LJ P2015dn, However as i can understand you r using External Wireless Router or Wireless network or jet-direct card if u r able to work fine on USB than printer printing mechanism is working fine.
If u connect the printer via wired network connection and it keeps on loosing IP address than it may be problem with onboard network card of the printer.
If printer keeps on loosing IP Address than try upgrading the firmware of the printer.
To check the firmware and IP Address of the printer print a configuration page by pressing and holding down green button for 6 to 7 seconds

turn on the printer sharing via the system preference panel on the computer that is on the system via usb.
Then on your wifi computer look for shared printers and you'll see your printer in the list under the host computer name... use that setting and it should fire up for you!
let me know how it goes...

Try connecting the USB cable directly to the computer not via a HYB.

Try another USB port on the computer.

If that doesn't solve the problem there is most likely a problem with the printer.
