Troubleshooting Tools 26

ENWW

When you first install the Jetdirect print server from the factory, 
all supported network protocols are enabled (or turned on) 
whenever you turn the printer on. 

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 and TCP/IP). 

●

provide better control over who prints to the printer by 
eliminating users from other networks who might accidentally 
route print jobs to this printer.

●

eliminate unnecessary information on the Jetdirect 
Configuration Page, which displays status information 
for all enabled protocols. 

●

display protocol-specific error conditions on the printer’s control 
panel for enabled protocols only. 

Protocols can be enabled or disabled on the print server through a 
variety of tools, such as Telnet, Web browser access to the embedded 
Web server, the printer control panel, and HP Web Jetadmin 
management software. For more information about these and other 
tools, refer to the applicable HP Jetdirect Administrator’s Guide 
located on the HP Jetdirect CD-ROM.
