Prettier printing

Going through pixmaps for the profile was not needed and was making our prints
look very pixelated.

In Qt4, QWidget child classes are printed as bitmaps. So appart from
changing the code to print the tables to use a QGraphicsView instead,
there is nothing we can do, so the rest of the printing is still done as bitmaps.
