HP 600N HP JetDirect 600N Print Server Hardware Installation Guide - 5969-6858 - Page 28

After you have configured the HP JetDirect card through the control panel, you may still need to complete the configuration of your computer and network operating system for printing. For more information, see the HP JetDirect software installation instructions included with this product. If you reconfigure the card-for example, you disable a network protocol-your configuration is saved on the card and is maintained even after the printer is turned off and back on again. To Restore Configuration Default Values You can restore default values by performing a cold reset on your printer. See your printer documentation for instructions. (Note: To perform a cold reset on some HP LaserJet printers, turn off the printer and then hold down [Go] as you turn the printer back on.) Resetting your printer restores both your printer and JetDirect configuration to their factory default values. To verify HP JetDirect default values have been reset, print a JetDirect configuration page (see chapter 2). To Enable or Disable Network Protocols When you first install the card from the factory, all supported network protocols are enabled (or turned on) when you turn the printer on. If a network protocol is enabled, the card may actively transmit on the network even when the protocol is not in use. This may increase network traffic slightly. To eliminate unnecessary traffic, you can disable unused protocols. Disabling unused protocols lets you: G reduce network traffic by eliminating broadcast messages from unused protocols (for example, IPX/SPX and TCP/IP). G provide better control over who prints to the printer by eliminating users from other networks who might accidentally route print jobs to this printer. 3-2 Control Panel Configuration
