Problem printing from NT to printer attached to LInux box

[Carlton Davis]

I installed Samba 2.2.2 on my Linux box. The smb.conf file is as shown 
below. The permission on /var/spool/lpd/lp is set to 755; ie, it is 
writable only by the owner, which is lp. With the setup as is, when I
try to print from the NT machine, the smb log on the Linux box
indicates the following error: " print_job_start: insufficient
permissions to open spool file /var/spool/lpd/lp".
If I set the permission on /var/spool/lpd/lp to 777, I can
print; however, for obvious security concerns, this solution is
undesirable.

Could someone inform me as to what is the correct way to set things up
to allow printing from my NT machine without making /var/spool/lpd/lp
writable by all. My smb.conf file is shown below.

[global]
   netbios name = bert
   workgroup = WORKGROUP
   hosts allow = 10.10.10. 127.
   load printers = yes
   max log size = 50
   security = server
   password server = 10.10.10.8
   socket options = TCP_NODELAY 

[printers]
   comment = All Printers
   path = /var/spool/lpd/lp
   browseable = yes
   guest ok = yes
   writable = no
   printable = yes
   public = yes
   write list = @administrators,root   


Thanks in advance.
