TCP/IP Troubleshooting

If you are using TCP/IP and cannot print to the Print/Fax server and
you have checked the hardware and network as described in the
previous steps, then check the following:

Turning off the printer and then on 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/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/Fax 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.

It is always a good idea to try following in order to eliminate
the possibility of setup errors.
