Verify network cabling, connections, and router configurations. Verify that network cable lengths meet network specifications.

For wireless print servers, verify that the wireless network parameters are set correctly.

Verify that the printer is attached to the network through the appropriate HP Jetdirect print server port and cable. Check each cable connection to make sure it is secure and in the right place. If the problem continues, try a different cable or network port on the hub or switch.

For proper operation, the link speed and communication mode on the print server must match the network.

Depending on the print server and printer/MFP device, indicator lights can identify the link speed used. If LEDs are used, verify that either the 10 Mbps, 100 Mbps, or 1000 Mbps link speed light is on. If all link indicators are off, then a proper link is not established.

The configuration page also contains the port configuration and auto-negotiation settings on the print server. Print and view the configuration page to verify proper settings.

The network must support the EAP method configured for use on the print server.

Verify the configuration of the network’s 802.1X port. If it does not allow guest or temporary access, you might need to pre-configure the HP Jetdirect print server for 802.1X operation before connection to your network. Do this using an isolated LAN, or through a direct computer-to-printer connection using a cross-over cable.

Make sure the applications are compatible, installed correctly, and use the correct printer drivers.

The problem might be workstation-specific. Check the workstation network drivers, printer drivers, and redirection (capture in Novell NetWare).

Check your system for proper network operating system setup.

Check the status of the network protocols on the HP Jetdirect configuration page. See HP Jetdirect configuration pages for information on the configuration page. (On TCP/IP networks, you can also use the embedded Web server to check status of other protocols. See Embedded Web server (V.38.xx))

See HP Jetdirect configuration pages for a list of error messages.

To print directly, use the following Telnet command:

telnet <IP address> <port>

In the example, <IP address> is the IPv4 address assigned to the HP Jetdirect print server and <port> is 9100, the default printing port of the print server.

In the Telnet session, type in data and press Enter. The data should print to the printer (a manual form feed might be required).
