Avoids the process for a filter (cat) which is doing nothing for you.
While this is true in Centos, if one moves between *nix implementations, it is an unsafe habit to have (using lpr directly), as in early Unix implementations, lpr is occasionally set to _delete_ the file it has just completed printing.
