When the HP JetDirect print server is powered on, it broadcasts a BOOTP request that contains its MAC (hardware) address. A BOOTP server daemon searches the /etc/bootptab file for a matching MAC address, and if successful, sends the corresponding configuration data to the JetDirect print server as a BOOTP reply. The configuration data in the /etc/bootptab file must be properly entered. For a description of entries, see “Bootptab File Entries”.
The BOOTP reply may contain the name of a configuration file containing enhanced configuration parameters. If the HP JetDirect print server finds such a file, it will use TFTP to download the file and configure itself with these parameters. For a description of entries, see “TFTP Configuration File Entries“. Configuration parameters retrieved via TFTP are optional.
Note
HP recommends that the BOOTP server be located on the same subnet as the printers it serves.
BOOTP broadcast packets may not be forwarded by routers unless the routers are properly configured.
CAUTION
Community names (passwords) for your printer are not secure. If you specify a community name for your printer, select a name that is different from passwords used for other systems on your network.
