13 - 5 TROUBLESHOOTING
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.
