13 - 5 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.

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).

Make sure that the TCP/IP protocol of the Print/Fax server is enabled.

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.

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.

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.

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.
