[Selin Can]

Hi,
I have a web application to print some data.My reporting data exist in a
panel.
I want to print the panel when i click button.
But if the panel width is bigger than printer page size like A4,I loss some
data .

Is there any way to print fix the panel size to A4 or to scale the panel.
How can i print without lossing data.
