Table 6-1 Summary of HP Jetdirect security features (continued)

Printer Control Panel Lock

●

Selected HP printers provide a control panel lock that prevents access to HP Jetdirect print server configuration

parameters. In many cases, management applications (such as HP Web Jetadmin) can remotely set the lock. To determine

whether your printer supports a control panel lock, see your printer documentation.

Configuration Precedence Table

●

To control the configuration of various TCP/IP parameters using the different tools supported by the print server, a

Configuration Methods precedence table is provided. Access the precedence table using the HP Embedded Web Server.

By default, manual configuration methods have precedence over other methods (such as DHCP or TFTP). By changing the

precedence order, the control of configuration parameters can be enhanced.
