Servidor de Impressao RH 9.0 CUPS

Pessoal,

Tenho uma rede windows com dominio.
Recentemente consegui uma maquina para instalar o Linux e uma HP710c para testar um servidor de impressao.

O meu /etc/samba/smb.conf esta assim:
=============== Global Settings =======================
[global]
workgroup = PRINTER
server string = Samba Printer Server
printcap name = /etc/printcap
load printers = yes
printing = cups
log file = /var/log/samba/%m.log
max log size = 0
security = user
encrypt passwords = yes
smb passwd file = /etc/samba/smbpasswd
unix password sync = Yes
passwd program = /usr/bin/passwd %u
passwd chat = *New*password* %n\n *Retype*new*password* %n\n *passwd:*all*authentication*tokens*updated*successfully*
pam password change = yes
obey pam restrictions = yes
socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
dns proxy = no
#=== Share Definitions ==============================
[homes]
comment = Home Directories
browseable = no
writable = yes
valid users = %S
create mode = 0664
directory mode = 0775

[printers]
comment = All Printers
path = /var/spool/samba
browseable = yes
public = yes
print ok = yes
writable = yes
printable = yes
available = yes
admin users = all

[Rede]
available = yes
browseable = yes
public = yes
guest only = no
writable = yes
allow hosts = all
only user = no

Eu consigo mapear a impressora de uma estacao windows2000 somente colocando usuario e senha(que eu registrei no samba), depois de mapeada a impressora, eu mando imprimir mas nada acontece.
Qual sera o problema disso?
Alguem ja efz servidor de impressao com o RH 9.0?

Obrigado
