samba - Oct 2004 - Not able to upload printer drivers for WinXP/2k

Hi all,
        I've just realized that using Windows APW (Wizard)it would be
possible to upload/install my usb-printer drivers shared on my linux
samba server (2.2.1a).
  
Tried doing so ,but came across lot of failure messages like      
'Windows could not install driver ....' in the final step of the wizard
where it asks for drivers.

afore is my smb.conf

------------------------

[global]
security=user
netbios name=PRINT-SERVER
workgroup=WORKGROUP
load printers=yes
printer admin=user
printcap name=/etc/printcap
printing=cups
[print$]
path=/usr/local/samba/print
read only=yes
browseable=no
guest ok=yes
write list=user
[Lexmark]
path=/var/disk1/print/spool
read only=no
max connections=50
printer=prn
disabled=no
printable=yes
browseable=yes
comment=Lexmark  Z700-P700 Series

Can some one send me how I should go about uploading from a WinXP host
and is there some thing incorrect in what I'm doing?
