Yes possible. While developing the Form. you have to put the back side content in the Saperate new page. Based on your requirement you need to call that page. But again Back side is basis people.
Normally people will ask like Terms and Conditions will be last page.
Or Every page last page.
What ever it.
in smart form u have to call that page. But printing backside or front side. basis people has to do.
Suppose.
form1 front end page
form2 second page (It has to display back of the form1).
You have to develop back page as separate page.You have to call after first page.
if u open the print preview. total form will comes like
form1
from2
But But while printing only printer setting we can print back or front.
Ask basis person for printing the data. I hop in coding no need to mention back or front.
