CONTROL COMMANDS LIST

Select bit-image mode

[Format] ASCII ESC
Hex 1B
Decimal 27
[Range] m = 0, 1
0 ≤ nL ≤ 255
0 ≤ nH ≤ 3
0 ≤ d ≤ 255
k = nL + nHx255
[Default] None
[Description] Selects a bit-image mode using m for the number of dots specified by
(nL + nH x 256) as follows :
m Mode Number of bits for vertical data
0 8-dot single-density
1 8-dot double-density
[Notes] Data (d) specifies a bit printed to 1 and not printed to 0.
If the bit image data exceeds the number of dots to be printed on a line,
the excess data is ignored.
The bit-image is not affected by print mode (emphasized, double-strike,
underline, character size), except for upside-down printing mode.
After printing a bit image, the printer processes normal data.
When printing multiple line bit images, selecting unidirectional printing mode
with ESC U enables printing patterns in which the top and bottom parts are
aligned vertically.
This command is used to print a picture or logo.
The relationship between the bit image data and the print result is as follows.

The modes selectable by m are as follows:
- "Vertical" is in the direction of paper feeding and "horizontal" is perpendicular
(at right angles) to the direction of paper feeding.
- The maximum number of dots for printing depends on a DIP Switch [DSW1-8] setting
and paper width. See the description of GS ( E <Function 5>, <Function 6> for details.

Turn underline mode on/off

[Format] ASCII ESC
Hex 1B
Decimal 27
[Range] n = 0, 1, 48, 49
[Default] n = 0
[Description] Turns underline mode on or off using n as follows:
n Function
0, 48 Turns off underline mode
1, 49 Turns on underline mode (1-dot thick)
2, 50 Turns on underline mode (1-dot thick)
[Notes] The printer cannot underline the space set by HT
Changing the character size does not affect the current underline thickness.
When underline mode is turned off, the following data cannot be underlined,
but the thickness is maintained.
This command and bit 7 of ESC ! turn on and off underline mode in the
same way.
