		[27,63,n,m] D				ESC Y, and ESC Z commands.
						n: specifies the former graphic type assigned
						by "K", "L", "Y", or "Z"
						m: specifies the new graphic type in table below
			m		Graphic Type		Number	Maximum	Horizontal
							of Pins	Columns	Density
			0		Standard-density		8	816	60
			1		Double-density		8	1632	120
			2		Double-speed double-density*		8	1632	120
			3		Quadruple-density *		8	3264	240

			40		Hex-density*		24	4896	360
		Note (*): Horizontal adjacent dots can not be printed.
[42]	ESC @	[1B,40] H		[27,64] D		Initializes printer.
[43]	ESC A n	[1B,41,n] H		[27,65,n] D		Sets line spacing to n/60" (0≤ n≤ 127).
[44]	ESC B n1 n2...	[1B,42,n1,n2,...n16,00] H				Sets vertical tab positions beginning from n1 and end
	n16 NUL	[27,66,n1,n2,...n16,0] D				with NUL [00]H. n1=1 is at the second line from TOF.
						Downloaded data and communication buffer are not
						cleared. The current print line becomes the top of the
						form.
[45]	ESC C n	[1B,43,n] H		[27,67,n] D		Sets page length in line unit (1≤ n≤ 127).
						The current print line becomes TOF (top of form).
[46]	ESC C NUL n	[1B,43,00,n] H [27,67,0,n] D				Sets page length in inch unit (1≤ n≤ 22).
						The current print line becomes TOF (top of form).
[47]	ESC D n1	[1B,44,n1,n2,...n32,00] H				Sets horizontal tab position (1≤ n≤ 255).
	n2...n32 NUL	[27,68,n1,n2,...n32,0] D				n indicates the number of spaces from the left margin
						with the character width at the command execution.
						n1=1 is at the second column from the left margin.
[48]	ESC E	[1B,45] H		[27,69] D		Sets emphasized character mode.
[49]	ESC F	[1B,46] H		[27,70] D		Cancels emphasized character mode.
[50]	ESC G	[1B,47] H		[27,71] D		Sets double strike character mode.
[51]	ESC H	[1B,48]H [27,72] D				Cancels double strike character mode.
[52]	ESC J n	[1B,4A,n] H [27,74,n] D				n/180" linefeeds after printing (0≤ n≤ 255).
[53]	ESC K n1 n2	[1B,4B,n1,n2,data] H				Prints the 8-pin Standard-density graphic mode.
	data	[27,75,n1,n2,data] D				The total number of dots in the data is set by
						n1+n2 x 256.
[54]	ESC L n1 n2	[1B,4C,n1,n2,data] H				Prints the 8-pin Double-density graphic mode.
	data	[27,76,n1,n2,data] D				The total number of dots in the data is set by
						n1+n2 x 256.
[55]	ESC M	[1B,4D] H		[27,77] D		Selects elite (12cpi) mode.
						The condensed pica character (17.1 cpi) also becomes
						the condensed elite character (20 cpi).
[56]	ESC N n	[1B,4E,n] H [27,78,n] D				Sets skip over perforation (1≤ n≤ 127).
						n specifies the number of lines to be skipped at the
						end of a page.
		For example: If the line spacing is 1/6 inch and the page length is 66 lines,
		an ESC N 6 command causes the printer to print 60 lines, then skip 6 lines.
		The space to be skipped is 1 inch (1/6 inch x 6).
