This command is eective for all characters (except for HRI characters).
In standard mode, the vertical direction is the paper feed direction, and the horizontal direction is perpendicular to
the paper feed direction. However, when character orientation changes in 90 degree clockwise-rotation mode, the
relationship between vertical and horizontal directions is reversed.
In page mode, vertical and horizontal directions are based on the character orientation. When characters are enlarged
with dierent sizes on one line, all the characters on the line are aligned at the baseline.
The select print mode (1B 21 n) command can also select or cancel double-width and double-height modes. However,
the setting of the last received command is eective.
Exceptions
If n is out of the dened range, this command is ignored. This command is only valid for the receipt station.
