FreeBSD6 or samba, printing blank end page

[Dave]

Hello,
    I've got a Freebsd6 print server that has two printers attached to it, 
both hp models one a deskjet the other a laserjet. Both are exhibiting the 
same behavior, whenever i print something from a windows box, xp in this 
case, the windows boxes use windows printer drivers and samba3 for this, the 
document i want is printed and removed from the unix print queue no problem. 
The issue, minor though annoying, is at the end of every document the 
printer ejects the last page as it should, but then i get one blank page 
spat out of the printers. I am unsure how to debug this, if it's samba, or 
freebsd or the unix script i am using for unix to talk to the printer. Any 
help appreciated. My config is below.
Thanks.
Dave.
