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:
Turning off the printer and then 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 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 If you used BRCONFIG, NCP or to enter the IP address, make
sure that you exited the remote console properly with a CTRL-
D or EXIT and that you turned the printer off and then again (it
may take up to two minutes for the IP address to take effect).
3 Make sure that the TCP/IP protocol of the print server is
enabled.
4 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 server name
matches the name in the
/etc/hosts file.
5 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.
6 Also verify that host computer and the print server are either on
the same subnet, otherwise that the router is properly
configured to pass data between the two devices.
It is always a good idea to try following in order to eliminate
the possibility of setup errors.
