This is just debug output, and should be removed, of course.

At first, I allowed to change the username, than reverted it because I
thought this might be misused regarding print quota. Letting the user
change its identity assumes that on the other end, the CUPS server WILL
ask for a password. If the server is not configured to ask for a password,
any user can use any identity to print, it's really "too easy".
For me, it's a very small code change, but I prefer to have external
opinions before making changes.
