Because you haven't enabled file URIs in the cupsd.conf file!

Back in CUPS 1.1.15 (or so) we added the FileDevice directive to
cupsd.conf to both prevent common security issues with file URIs
and to deprecate their use (file URIs do not behave exactly like
other devices - they are there primarily for testing purposes...)
