Trying to share a printer with XP

[Gordon Charrick]

I've got an old Laserjet 6P. It prints fine in Fedora 6. I'm trying to 
get my windows machine to use it with no luck. Here's the section of 
smb.conf that uses it.

[printers]
    comment = All Printers
    path = /var/spool/samba
    printer = lj6p
# Set public = yes to allow user 'guest account' to print
    browseable = no
    printable = yes
    guest ok = yes
    public = yes

I can add the printer in windows just fine, but when I bring up the 
printer list it says "access denied" and I can't send anything to the 
printer. I get no messages at all in the logs and it's driving me crazy. 
Do I also need to do something with cups configuration? I have iptables 
turned off so it's not a firewall issue.
