[Samba] Printing ask password

[Collen Blijenberg]

WEll got the printing all up and working (bsd)
but we have 1 printer that is a little differend

i need to setup a network printer, and if someone wants to print to it
it should ask for a password (and/or username).
the idea is that a studend who wants to print, gives a print job, and
get's promted for a password, then the teacher have to aprove the
print by entering a password.

is this possible within samba (eg with pre exec command)
or mayby to make printing allowed by 1 user, and if an other tries to
print that he need to auth.again as a differend user ?

does someone has a clue,hint or sugestion ??
(little things might work asswell)

Greetings
