samba cups and turboprint problem

[Silvino B. Magalhaes]

Hello Linux Samba List,

I'm trying to print from windows client to an HP 695C printer on
the samba server, but this printer isn't visible from the clients
to install new printer, only machine are visible from network
browsing.

On the server (slackware 7.1) I got printing from all aplications
and testing printing. The printer is called tp0 and is the only
line on the /etc/printcap file.

When runing testprns tp0 /etc/printcap, tp0 is a valid printer.
I had installed cups (1.1.12) , turboprint (1.51) and samba (2.2.5)
from the source in this same order.

For compile samba, I used configure --enable-cups to include libcups.

If printing = cups and printcap name = cups is setting as suggestion
in man smb.conf, the clients can't autenticate on the samba server.

What is wrong in my smb.conf file ?
