Probably the line(s) you are putting out do not conform to the
format required - verify the output against the "man backend"
documentation and check the /var/log/cups/error_log file for
errors from cups-deviced.

The 1284 device ID is *not* required.  If you don't have one, then
don't provide it!  Just provide the make and model, which is enough
to support driver matching in the web interface.
