TCP/IP Troubleshooting
If you are using TCP/IP and cannot print to the print server and you have
checked the hardware and network as described in the previous steps, then check
the following:
It is always a good idea to try following in order to eliminate the possibility of
setup errors.
Turning off the printer and then again,
Deleting and recreating the print server and creating a new print queue in order to
eliminate the possibility of setup errors.
1. The problem may be the result of mismatched or duplicate IP address.
Verify that the IP address is correctly loaded into the print server (via the
configuration page. Make sure that no other nodes on the network have
this address (DUPLICATE IP ADDRESS ARE THE BIGGEST CAUSE
OF TCP/IP PRINTING PROBLEMS).
2. If you used BRCONFIG, NCP or to enter the IP address, make sure that
you exited the remote console properly with a CTRL-D or EXIT and that
you turned the printer off and then again (it may take up to two minutes
for the IP address to take effect).
3. Make sure that the TCP/IP protocol of the print server is enabled.
4. If you used rarp, make sure that you started the rarp daemon on any
workstation using the rarpd, rarpd-a, or equivalent command. Verify that
the /etc/ethers file contains the correct Ethernet address and that
the print server name matches the name in the /etc/hosts file.
5. If you used bootp, make sure that you started the bootp daemon on any
UNIX workstation and bootp is enabled (i.e., the "#" is removed from
the bootp entry) in the /etc/bootptab file is correctly configured.
6. Also verify that host computer and the print server are either on the same
subnet, otherwise that the router is properly configured to pass data
between the two devices.
