In fact I already had "BrowseLocalProtocols dnssd" in cupsd.conf in my
laptop (client) - and on checking the server machine in fact
avahi-daemon was already running - though I may need to change a
config somewhere to allow it to broadcast dns-sd?

I now have avahi-daemon running in the client laptop also but I don't
see any printers visible from the server in the local network - one
question I don't know is what port the dns-sd traffic needs - I need
to ensure that any required port is not blocked in the firewalls.
