How can I change page size for printing?

[Larry]

Hi my friends,

I'm writing a small program to print a form. The form is on customer sized
paper. I trying to use following code to change paper size, but it dosn't
work. Why??
There's always an error message: 'you can only change papersize when its
kind is Costom'. I did set Papersize.Kind to Custom. Thanks ahead for your
help.
