When calling render() on a QWidget and printing the result then the size of the print job can be quite large if there is a number of child widgets needing to be rendered. This is more apparant with Postscript printers but can happen on non-postscript printers too. The attached example shows this happening, if you print to a file then the size can be well over 5mb for a simple widget being rendered.
