Select Character Size
Selects the character height using bits 0 to 2 and selects the character width using bits 4
to 6, as follows:
Character Width Selection
Hex Decimal Width
00 0 1 (normal)
10 16 2 (two times width)
20 32 3 (three times width)
30 48 4 (four times width)
40 64 5 (five times width)
50 80 6 (six times width)
60 96 7 (seven times width)
70 112 8 (eight times width)
Character Height Selection
Hex Decimal Height
00 0 1 (normal)
01 1 2 (two times height)
02 2 3 (three times height
03 3 4 (four times height)
04 4 5 (five times height)
05 5 6 (six times height)
06 6 7 (seven times height)
07 7 8 (eight times height)
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 clockwise-rotation mode, the relationship between
vertical and horizontal directions is reversed.
In page mode, vertical and horizontal direction 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 (ESC !) command can also select or cancel double-width and
double-height modes. However, the setting of the last received command is effective.
