2. Restrictions in Page Mode

Mode, the commands ESC

(3) Upside-down character specification is invalid.
In Page Mode, characters and bit images can be rotated in units of
90 degrees several times to allow 4 different character or image orientations.

and images cannot be intensified or emphasized by duplicating dots.
(5) Underline specification is invalid.
Since characters and bit images can be freely overlapped in Page Mode,
underlining using ESC
