Create a Telnet connection
To use Telnet commands with the HP Jetdirect print server, a route is required from your workstation to the print server. If the print server and your computer have a similar IP address (the network portion of their IPv4 addresses match), a route probably exists.
If the IPv4 addresses do not match, you can change your workstation’s IPv4 address to match, or you can attempt to create a route to the print server. (If the print server is configured with a legacy default IP address such as 188.8.131.52, a route normally does not exist.)
Using Telnet to manually set an IPv4 address overrides dynamic IP configuration, such as BOOTP, DHCP, and RARP, which results in a static configuration where IP values are fixed. This might prevent BOOTP, DHCP, or RARP from functioning correctly.
When manually changing an IP address, you should also re-configure the subnet mask and the default gateway.
C:> ipconfig (on Windows 2000/XP/Server 2003)
The <Jetdirect IP address> is the IP address configured on the HP Jetdirect print server, and <system IP address> is the IP address of the workstation’s network card that is attached to the same physical LAN as the print server.
