As visio user I want to be able to print my diagrams over several pages with maximum magnification.
Current state: Now it's time consuming operation to move diagram and check magnification and move print check again.
Expected: I specify how many pages I could give for printing and visio automatically adjust zoom, paper orientation, diagram position, may be diagram rotation and slight reordering to make prints looks better.

Explanation:
Orientation - Some diagrams looks better on horizontal page orientation, some on vertical.
Zoom level: Now zoom function is unified and very simple. But for better printing (and may be layout) visio could use an algorithms from graphic editors with have an non linear scale algorithms. The main idea of this algorithms - is reduce space with low entropy. (such as gups) between diagram elements. Using such algorithms allow to slightly move objects on diagram to avoid printing over page borders.
Rotation - if diagram initially looks diagonal it could be optionally rotated before printing to fit page best way.
