Description	Move the print position to the next tab position. If no tab position is set (it is default setting), this command will be ignored The tab position is set by ESC D If the tab position exceeds the print area, printing position will be moved to the starting position of next line (Considering as a line is full, print the data and feed one line).
Reference	ESC D

LF

LF
Name	Print and feed paper
Format	ASCII LF Hex 0A Decimal 10
Description	Print the data in the printer buffer, then feed paper for one line according to the current line space settings. After printing, the print position moves to the beginning of the line.

Description	Set the right right-side character space is [n×0.125mm] For double width mode, the character right margin is double than normal mode. The command will not effective to Chinese characte
Default	n=0

ESC ! n(Ⅰ)

ESC ! n
Name	set the font type
Format	ASCII ESC ! n Hex 1B 21 n Decimal 27 33 n
Description	Set the font type (italic, border, bold, double width, double height, inverse or underline). And the bit definitions of parameter n are shown as follows table
Reference	ESC -, ESC E, GS !
Default	n=0

ESC ! n（Ⅱ）

Bit	On/off	Hex	Decimal	Function
0	off	00	0	Character type A (12×24)
0	on	01	1	Character type B (9×17)
4	off	00	0	Double-height mode off
4	on	10	16	Double-height mode on
5	off	00	0	Double-width mode off
5	on	20	32	Double-width mode on
7	off	00	0	Underline mode off
7	on	80	128	Underline mode on

• If set double-width and double-height at the same time, quadrupled thecharacter size.
• Can not underline the blank generated by HT or the rotate 90 character.
• The width of under line set by ESC -, have not affected by the character size.
• ESC M also can set character type.
• ESC – also can turn on/off underline.
• GS ! also can set character size.

ESC $ nL nH

ESC $ nL nH
Name	Set the absolute print position
Format	ASCII ESC $ nL nH Hex ESC $ nL nH Decimal 27 36 nL nH
Parameter Range	0≤nL≤255 0≤nH≤255
Description	Moves the print position to a location in a distance of (nL + nH × 256) dots from the starting position for printing
Reference	ESC \

ESC * m nL nH

ESC * m nL nH d1...dk
Name	Select bit-image mode
Format	ASCII ESC * m nL nH d1...dk Hex 1B 2A m nL nH d1...dk Decimal 27 42 m nL nH d1...dk
Parameter Range	m = 0,1,32,33 0≤nL≤255 0≤nH≤3 0≤d≤255
Description	Stores the bit image data in the print buffer using the mode specified by bit image mode m, nl and nh specifies a bit image in the horizontal direction as(nl+256×nh) dots, [d]k specifies the bit image data (column format) k indicates the amount of bit image data, but it does not need to be transmitted..
Note	If m is out of Parameter Range, the nL and the other data will regard as the normal data. If the bit image exceeds one line of print area, the excess part will be Ignored. Data [d]k specifies a bit printed to 1 and not printed to 0. Bold, double-strike, underline, character size, upside-down, black/white command will not affect to the command.

ESC - n

ESC - n
Name	Turn underline mode on/off
Format	ASCII ESC - n Hex 1B 2D n Decimal 27 45 n
