I copied the following piece of code to my form :

* Know total pages to print
DEFINE WINDOW x FROM 1,1 TO 20,20
ACTI WINDOW x
REPORT FORM fmto_fact_prueba
vp_TotHojas= _pageno
RELEASE WINDOW x

vp_TotHojas is Set To 3, but when I send to printer, I get 4 Hojas printed.
Printer Is Epso LX 300+II

What I need to do to get correct number of total pages before to print ?

Thanks
