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.
