printing problem

[GIUSEPPE GIACOMINI]

I have a linux box with samba 2.0.3 acting as PDC and print server
for 15 NT-Workstation.

This is my problem:

When I submit a print job from an NT-WS, samba writes in the spool 
directory the file to be printed in the form
of: USERNAME.a29051 (for the files printed from an internet browser
this name become the URL)

Is it possible to obtain directly the real name of the file printed
instead of USERNAME.a29051    (as it occurs when I print a file from a NT
client to an NT-server)
