Comment (by waltweltonlair):

 Discussion of the problem:

 When creating the printed view the DPI is set to that of the printer,
 which is typically much higher than the screen.  The requested resolution
 is therefore increased.  During normal screen viewing my DPI was 96 and
 the requested raster size was about 384x527 pixels.  When printing the DPI
 was 600 and the requested raster size was about 6814x4759 pixels.  The
 size of the array needed to allocate this raster (32bpp x 6814 x 4759 =
 129711304 bytes) exceeds the maximum allowed value (16777216), and
 therefore the raster is not drawn.

 The fix was simply to ensure that the requested size of the raster doesn't
 exceed the maximum allowed value.
