Thanks Michael, the 'Listen' problem is cured by using '127.0.0.1:631'
I am logged on as 'root' the error log is below when I try to add a printer.  The printer is created but does not work.  I think you are right about permissions but I am not sure who the owner/group should be and what permission should be.
