Although a Telnet connection may be protected by an administrator password, Telnet connections are not secure. For networks with high security levels, Telnet connections can be disabled on the print server using other tools (for example, TFTP, embedded Web server, or HP Web Jetadmin software). Creating a Telnet Connection To use Telnet commands with the HP Jetdirect print server, a route must be available from your workstation to the print server. If the print server and your computer have a similar IP address, that is, the network portion of their IPv4 addresses match, chances are that a route will exist. If their IPv4 addresses do not match, then you can either change your workstation's IPv4 address to match, or you can try an operating system command to create a route to the print server. (For example, if the print server is configured with a legacy default IP address 192.0.0.192, a route will not likely exist.) On Windows systems, you can use the "route" command at a Windows command (DOS) prompt to create a route to the print server. For information on system command prompts, see your Windows online help. On Windows NT systems, the command prompt utility is in the Programs folder (click Start, Programs, Command Prompt). On Windows 2000/XP/Server 2003 systems, it is in the Accessories folder in the Programs or All Programs folder. To use the route command, you will also need the IPv4 address of your workstation. To view it, you can enter the appropriate command at the command prompt: C:\> ipconfig (on Windows NT/2000/XP/Server 2003) C:\> winipconfig (on Windows 98) To create a route from the system command prompt, enter the following command: route add where is the IP address configured on the HP Jetdirect print server, and is the IP address of the workstation's network card that is attached to the same physical LAN as the print server. For example, to create a route from your workstation with IP address 169.254.2.1 to a print server with a default IP address of 192.0.0.192, try this command: route add 192.0.0.192 169.254.2.1 CAUTION Using Telnet to manually set an IPv4 address will override dynamic IP configuration (such as BOOTP, DHCP, or RARP), resulting in a static configuration. In a static configuration, the IP values are fixed and the operation of BOOTP, DHCP, RARP and other dynamic configuration methods may no longer function. Whenever you are manually changing an IP address, you should also reconfigure the subnet mask and default gateway at the same time.

Although a Telnet connection may be protected by an administrator password, Telnet connections
are not secure. For networks with high security levels, Telnet connections can be disabled on the
print server using other tools (for example, TFTP, embedded Web server, or HP Web Jetadmin
software).
Creating a Telnet Connection
To use Telnet commands with the HP Jetdirect print server, a route must be available from your
workstation to the print server. If the print server and your computer have a similar IP address, that
is, the network portion of their IPv4 addresses match, chances are that a route will exist.
If their IPv4 addresses do not match, then you can either change your workstation's IPv4 address to
match, or you can try an operating system command to create a route to the print server. (For
example, if the print server is configured with a legacy default IP address 192.0.0.192, a route will not
likely exist.)
On Windows systems, you can use the “route” command at a Windows command (DOS) prompt to
create a route to the print server.
For information on system command prompts, see your Windows online help. On Windows NT
systems, the command prompt utility is in the
Programs
folder (click
Start
,
Programs
,
Command
Prompt
). On Windows 2000/XP/Server 2003 systems, it is in the
Accessories
folder in the
Programs
or
All Programs
folder.
To use the route command, you will also need the IPv4 address of your workstation. To view it, you
can enter the appropriate command at the command prompt:
C:\> ipconfig
(on Windows NT/2000/XP/Server 2003)
C:\> winipconfig
(on Windows 98)
To create a route from the system command prompt, enter the following command:
route add <Jetdirect IP Address> <system IP Address>
where
<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.
For example, to create a route from your workstation with IP address 169.254.2.1 to a print server
with a default IP address of 192.0.0.192, try this command:
route add 192.0.0.192 169.254.2.1
CAUTION
Using Telnet to manually set an IPv4 address will override dynamic IP
configuration (such as BOOTP, DHCP, or RARP), resulting in a static configuration. In a static
configuration, the IP values are fixed and the operation of BOOTP, DHCP, RARP and other
dynamic configuration methods may no longer function.
Whenever you are manually changing an IP address, you should also reconfigure the subnet
mask and default gateway at the same time.
