print receipt on third segement of page and move to next segment

[Chris]

We have to print receipts that are printied on pre perforated sheets with
three blanks per letter size page. If we print only one receipt the receipts
print correctly but the page is form feed out of the printer where as we
want it to just move to the next increment on the page ready for the next
receipt to be printed. Any pointers on how to set this up.
Thanks
Chris
