Thanks. I completly forgot: CUPS constructs a destination from a printer's Service (Bonjour) Name by replacing a dash (-) with an underscore (_). It then adds an underscore (_) to the end. (It has stopped doing the latter in the most recent version, I thnk). I will scub the third method. It is too involved to explain how to reverse what is in the implicitclass URI just for resolving. avahi-browse seems the way to go for your purpose. BTW. I am interested in how using /usr/lib/cups/backend/snmp went. Its drawback is that not all printers provide an snmp service. -- Brian.
