The "proper" way would be to use a PPD file with the following
cupsFilter line:

     *cupsFilter: "text/plain 0 -"

You could also use an interface script and have it reject jobs
based on the CONTENT_TYPE environment variable.  However, that
would basically allow users to submit jobs and have them disappear
siliently - the PPD method will return an error immediately...
