9) Underline set/reset : <<ESC - n>>
Code
: [1B] h + [2D] h + n
* [00

n
≤
02 ]h
Description
: Sets and resets the underline
Explanation
: Underline is valid for all characters except for the
area skipped by horizontal tab. Also Underline is not valid for
90
°
rotated character.
* Underline is verified with n value as shown bellow.
n(hex)
Type of underlines

Set two dot underline
The default value of “n” is [00] h.
10) 1/6th of an inch line feed pitch : << ESC 2>>
Code
: [1B ] h + [32] h
Description : sets one line feed to 1/6th of an inch.
11) Sets smallest pitch line feed : << ESC 3 n >>
Code
: [1B ] h + [33 ] h + n
* [00
≤
n
≤
FF] h
Description : sets a line feed pitch to n/203rd of an inch.
*The height of character for a line (24/203 inch for normal character
print) is sent by line feed. If the value of height is set by “n” below
the height of character, the same space with character height is
sent by line feed.
* The default value of n is < 22 >h
12) Printer initialization
: << ESC @ >>
Code
: [1B ] h + [ 40 ] h
Description : Clears the data stored in the print buffer and resets
each setting to default values.
It does not clear the data stored in the internal receive buffer.
For each mode status in each setting function, refer to section 5.3
the mode status for setting function, [ESC @]. It is stored in the
internal receive buffer and activated in sequential.
13) Horizontal tab position set
: << ESC D n1 n2 ---
NUL >>
Code
: [1B ] h + [44] h + n1+ n2+
…
+ [00 ] h
*[00
≤
n
≤
FF ] h
Description : sets the horizontal tab position
1. “n” indicates the digits number from the left. In this case
n = tab position - 1.
2. Tab position is set at the location of character width x n from
the beginning of a line. The character width in this case
includes character right space. When double width function
is set, then the width becomes double of ordinary character.
3. Maximum number of tab positions is 32. If setting exceeds
32, then the exceeded values are neglected.
4. < ESC D NUL > clears all tab positions being set. After
the tab is cleared, horizontal tab will be ignored.
5. Default value is set at every 8 characters of font A (at 9
th,
17th, 25th and 33rd digit).
