In the case when the printer was not autodiscovered (e.g. IP address specified explicitly with -p 192.168.1.234), the parameter port will be None, and the intended default behavior will depend on the local system database (e.g. /etc/protocols) having an entry for pdl-datastream.
Add port 9100 as the intended fallback port when this is missing.
