Save data on click of PRINT and Print it later

Save data on click of PRINT and Print it later

I am developing window form application in c#. In that app, I have 20 i/p
and 20 o/p forms. So in each 20 o/p form, i have print button. Right Now,
when i click on print it will print document. But I don't want to do that.
I need some functionality so that when i click on print button on each n
every page, it will store data in some memory. And then i will put button
as 'PRINT ALL'. So it will print all form's output.
Don't have any idea how to achieve this functionality.? Please help me.
Thanks, Prashant
