This bug report originated from issue QTBUG-4898 http://bugreports.qt.nokia.com/browse/QTBUG-4898 --- Description --- Printing to pdf scales the content, so it have the wrong size on screen, and in print. This have been reproduced with HTML content but a simple QPainter::drawRect() test displays (slightly) wrong on screen, but prints correctly. It happens on both Windows and Linux. When a certain size is set in inches (or cm) in the HTML document, this is not respected in the final pdf document. <p>The examples/webkit/previewer/ example demonstrates the behavior with the attached file.</p>
This looks like bug #33657 to me which is though not related to PDF printing/scaling.
