Yes, but all jobs are "authenticated as him" only regarding the Samba
authentication.

The problem is that when the smb backend runs, it cannot open
a dialog with the user who had submitted the print job to do the
authentication regarding Samba because the backend runs as user "lp"
(or "root" if cupsd runs as root) and in general it is not possible
that the user "lp" opens a dialog with another user.
Additionally the job may have to wait several hours in the queue
until it becomes processed and in the meantime the user who had
submitted the job may have logged out.

The solution is to do the user authentication in CUPS:
Specify appropriate authentication settings in /etc/cups/cupsd.conf
for appropriate "Location(s)", see the "CUPS Software Administrators
Manual".

This way the CUPS printing dialog tools (e.g. "lp", "kprinter",
"gtklp", "xpp") can do the user authentication directly with the user
who submits the print job when he submits the print job (and not
after the job was submitted).
