 What about configuring CUPS from the browser? At least I am used to it.
 And the need for two browsers (a TorBrowser and, say, a vanilla Fx) bears
 the big risk that the users mess things up. So, if we see the need for
 removing "access" to 127.0.0.1 from the outside then we should make sure
 that the user itself is still able to reach things on 127.0.0.1 IMO.
