o You have to specify -o raw

o -o raw doesn't work for remote queues

o You can make truly raw printing the default by modifying
  /etc/cups/mime.types and /etc/cups/mime.convs



as the default type (no recognizers) to mime.types.  Add:

application/octet-stream        application/vnd.cups-raw        0       -

to mime.convs.
