This command is effective 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
In page mode, vertical and horizontal directions are based on the character orientation. When characters are enlarged with different 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
Exceptions
If n is out of the defined range, this command is ignored.
In native mode, the vertical direction is limited to 7 (seven times height) when Tall or ColorPOS® font is selected. If 8 (eight times height) is selected, the results are unspecified.

In A793 emulation, this command is discarded and not put into print buffer.
