Data Structure	ASCII		ESC "."		<c>	<v>	<h>	<m> <nL> <nH> <d1>...<dx>
	hex.		1B	2E	<c>	<v>	<h>	<m> <nL> <nH> <d1>...<dx>
	dec.		27	46	<c>	<v>	<h>	<m> <nL> <nH> <d1>...<dx>
Description	Valid values:
	c = 0
	c = 1
	v = 10, 20
	h = 10, 20
	m = 1, 8, 24
	0	≤ nL	≤ 255
	0	≤ nH	≤ 127
	0	≤ d ≤ 255

This sequence supports following print densities:

v	h	v (dpi)	h (dpi)	m
20	20	180	180	1, 8 or 24
20	20	180	360	1, 8 or 24
10	10	360	360	1, 8 or 24

“ESC .” allows printing dot graphics in raster format. A compression algorithm is provided for multiple printing of a particular byte of data.
