[Samba] Samba 3RC2 printer problem with windows machines

[antonio]

I am not an experienced Samba user, I apologize for that
I upgraded to Samba 3.0RC2 (my system is RedHat 9.0, fully upgraded).

I used to print from my Windows machines to my Epson printer connected 
to my Linux box with previous version of Samba: I didn't change any 
setting on my Windows machine.

Network printer port is //PC233/epson on my Win machines, driver of 
printer is installed and working properly.
When I try to print, my Linux server works for a while (red light 
flashing), but I don't get any output: what I find funny, is that if i 
re-connect the printer locally to my Win machine I get a "local" queue 
with jobs sent through the network, that makes me crazy.
Herebelow you will find my samba.conf file.Any clue???

Tnx for help

Antonio
