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.
