NOTE: Telnet use and support depends on the print server product and the printer/MFP device in which it is installed. Telnet might not be supported on
If you are configuring an HP Jetdirect wireless print server, this section assumes that a wireless network connection is established.
Although you can protect a Telnet connection using an administrator password, Telnet connections are not secure. For networks with high security requirements, you can disable Telnet connections on the print server using TFTP, the HP Embedded Web Server, or HP Web Jetadmin.
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 192.0.0.192, a route normally does not exist.)
CAUTION: 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
On Microsoft Windows systems, you can use the route command at a Windows command (DOS) prompt to create a route to the print server.
For information about system command prompts, see the Microsoft Windows online help. On Microsoft Windows XP, Windows Server 2003, or Windows Server 2008 systems, it is located in the Accessories folder in the Programs or All Programs folder.
To use the route command, you need the IPv4 address of your workstation. To display it, enter the appropriate command at the command prompt:
C:\> ipconfig (on Microsoft Windows XP, Windows Server 2003, or Windows Server 2008)
To create a route from the system command prompt, use the following:
route add <Jetdirect IP Address> <system IP Address>
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.
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, enter the following:
route add 192.0.0.192 169.254.2.1
