How to get the total number of pages we sent to printer in system.drawing.printing?

Question

Hi all,

I need to print the format which is given below in each and every page i sent to the printer.

                           (current pageNo)/(TotalPageNo)

But i cannot predict the total number of page that my will occupy.At the same time once i sent the page to printer i cannot get it back after that.

Please provide me the solution if u know.

Thanks
