CUPS printing problems

[Jeff Vian]

I have recently added an FC5 system to my home network.
I already have an FC4 server that has all my printers connected and I
want to not have to move them.  I want to have all machines on my local
LAN able to print to this server.
Note: I am not running samba since I have no windows systems to deal
with.

Printing from the local machine works, so it seems this is related to
enabling 

I have gone to the CUPS documentation and it seems that I should be able
to add a simple "Listen IP:port" in the cupsd.conf file and it should
work.
Whenever I try adding this option in the conf file then restarting cups
it fails with "child exited with error 98!", as if the syntax was wrong.
I cannot see the error, and what I have is like the example given in
the .conf file but it just fails.

Without the Listen option, the access_log shows me that the printing
attempt from the remote system fails with a 403 error.

Any pointers to the obviously simple fix for my blind eyes? 

NOTE: SElinux is presently disabled on both systems and iptables is not
running.
