Controlling Network Protocols
The HP Jetdirect print server can simultaneously support multiple network communication protocols.
This allows network computers that may be using different protocols to communicate with the same
printer.
Each protocol used on the print server may require some configuration before the printer can
communicate on the network. For some protocols, required parameters are automatically sensed and
user-specified settings are not needed. However, for other protocols, there may be many parameters
to configure.
Enable or Disable Network Protocols
By factory default, only the TCP/IP network protocol is enabled.
If a network protocol is enabled, the card may actively transmit on the network even when there are
no computers on the network that use the protocol. This may increase network traffic. To eliminate
unnecessary traffic, you can disable unused protocols. Disabling unused protocols lets you:
●
reduce network traffic by eliminating broadcast messages from unused protocols (for example,
IPX/SPX).
●
provide better control over who prints to the printer by eliminating users from other networks who
might route print jobs to this printer.
●
display protocol-specific error conditions for enabled protocols only.
To disable unused protocols through the device’s control panel menu, see
HP Jetdirect EIO Control
Panel Menus on page 21. For other tools, such as Web browser access to the embedded Web
server, or system command access to the embedded Telnet server, see the HP Jetdirect Print
Servers Administrator’s Guide for your print server model.
