It seems logical that 36th row is not visible fully onscreen with 600 height whereas for A4 having 72dpi with 595x842 pixels, it is visible but I was thinking about WYSWYG (what you see what you get) logic for printing and it's not printing exactly what we see so not sure if it's an issue. Maybe @prrace can share his thoughts if it's an issue or not
Otherwise looks ok to me.
