Cups network printserver protocol.

[Russ Pitman <rjp@belle.apana.org.au>]

In setting up a separate box as printserver for my small lan I'm confused 
about the printers.conf file. It is currently configured for the parallel 
port and works fine, but I understand that to comunicate to the other boxes 
it should be set up with the ipp proto.

If I do that print jobs get accepted and queued but never get printed. The 
error log shows no error. The last errorline reads
"Started backend /usr/lib/cups/backend/ipp (PID 902) for job 19" but nothing 
gets passed to the printer until the the configuration is reverted to the
parallel proto.

Cups documentation simply says that everything just works and I can't get 
clear references from Google.

Attached here is the bare bones of my various configs for the lan, I get 
error messages from the client boxes like lpstat -v
"get-printers failed server-error-service-unavailable" but not sure which 
end of the connection is responsible.

I must be missing something in the configs but where??

Thanks,
