it does seem odd that at some point and I can't tell if it was in Fedora
8 or Fedora 9, that they changed /etc/cups/mime.types and uncommented
out the application/octet-stream line.

It is fairly clear that the cups authors (now Apple) are aware of the
security implications of just allowing raw data to pass through
unchecked and of course a distro like Fedora can implement default
configuration files however they see fit.

The point was of course to help the OP figure out why he couldn't print
and it seemed likely that I had long ago 'uncommented' the raw printing
protection in my mime.convs and mime.types and some update at some point
simply over wrote the mime.convs file and never bothered leaving a
mime.convs.rpmnew file and I suspect that is what happened to the OP and
why it worked previously in Fedora-9 but not now in Fedora-10.

The samba link I provided gives a complete explanation including the
alterations necessary to enable raw printing.
