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 on again, Deleting and recreating the Print/Fax 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/
Fax 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
Make sure that the TCP/IP protocol of the print server is enabled.
3
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/Fax server name
matches the name in the /etc/hosts file.
4
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.
5
Also verify that host computer and the Print/Fax server are
either on the same subnet, otherwise that the router is properly
configured to pass data between the two devices.

UNIX Troubleshooting

1
Make sure that the /etc/printcap file (if applicable) is typed
in correctly. In particular, look for missing ":" and "\" characters,
because a small error anywhere in the file can have major
consequences. Also check the /usr/spool directory to make
sure that you have created a valid spool directory.
