		Notes
Function	(ASCII, Decimal, Hexadecimal)
Overscore	ASCII: ESC _ n	Prints a continuous overscore over all
	Dec: 27 95 n	text characters except for tab spaces.
	Hex: 1B 5F n	n=0 to 255
		n=odd: start overscore
		n=even: stop overscore
Graphics, 8-Pin Mode
For all 8-pin graphics
commands the number of
dot columns of graphic
data=n1 + (n2 x 256)
Single Density Graphics	ASCII: ESC K l h [graphics data]	Dot density 60 dpi horizontal, 72 dpi
	Dec: 27 75 l h [graphics data]	vertical.
	Hex: 1B 4B l h [graphics data]	Maximum data per line: ML390 Tur-
		bo=480: ML391 Turbo=816
		l,h=0 to 255: specifies amount of subse-
		quent Bit Image bytes received, calculat-
		ed as l + (h x 256).
Double Density Graphics	ASCII: ESC L l h [graphics data]	Dot density 120 dpi horizontal, 72 dpi
	Dec: 27 76 l h [graphics data]	vertical.
	Hex: 1B 4C l h [graphics data]	Maximum data per line: ML390 Tur-
		bo=960: ML391 Turbo=1632
		l, h=0 to 255: specifies amount of subse-
		quent Bit Image bytes received,
		calculated as l + (h x256).
Quasi-Double Density	ASCII: ESC Y l h [graphics data]	Same as low speed double density (120
Graphics	Dec: 27 89 l h [graphics data]	dpi), but printer can't put two adjacent
	Hex: 1B 59 l h [graphics data]	dots in the same row.
Quadruple Density	ASCII: ESC Z l h [graphics data]	Dot density 240 dpi horizontal, 72 dpi
Graphics	Dec: 27 90 l h [graphics data]	vertical. Printer can't put two adjacent
	Hex: 1B 5A l h [graphics data]	dots in the same row.
		Maximum data per line: ML390 Tur-
		bo=1920: ML391 Turbo=3264
		l,h=0 to 255: specifies amount of subse-
		quent Bit Image bytes received,
		calculated as l + (h x 256).
Set Aspect Ratio for Bit	ASCII: ESC n n	In PPR emulation, sets ratio of vertical to
Image Graphics	Dec: 27 110 n	horizontal dot density in bit image
