EN Summary of Font Selection by Characteristic 8-25
9 Orientation - for bitmap fonts the last criteria considered for the 
selection is its orientation. If two fonts still remain and match in all 
the above characteristics except orientation, that font which 
matches the current page orientation is selected.
If there is a soft font (highest priority location) available that 
matches all selection characteristics, but is not in the current 
orientation, and there is an identical font available in a cartridge 
or internal font (lower priority location) that is in the current 
orientation, the soft font is selected and rotated.
