Printing: remove silly white line at end of each page

Browse source 
QPrinter::pageRect() doesn't always return the correct value of the
printable area, which results in white horizontal lines of un-rendered
area at the bottom of each page, Use QPrinter::pageLayout() instead
which fixes the issue.

QPrinter::pageLayout() is added in QT 5.3, So use pageRect for previous
versions.
