Genicom GEK 00031B manual Gsm, Gss, S7C1T

GSM	Graphic Size Modification: This sequence will change the height
	and/or width of graphic characters. The first and second parameters
	are the percentages by which the height and width respectively will
	be multiplied. The default value for both p1 and p2 is 100 percent.
	General Command Syntax
	ESC [ Pn1;Pn2 SP B
	Decimal:	27 91 Pn1 59 Pn2 32 50
	Hex :	1B 5B Pn1 3B Pn2 20 42
	BASIC:	CHR$(27);”[“;Pn1;”;”;Pn2;” B”;

NOTE

Pn1 is a decimal value that specifies the height of the font as a percentage of the height set by the GSS sequence. Pn2 is a decimal value that specifies the width as a percentage of the width set by the GSS sequence. Fonts can be modified by two or three times their default height and two times their default width.

GSS	Graphic Size Selection: Sets the height and width of all characters
	that start after the control sequence.
	General Command Syntax
	ESC [ Pn SP C
	Decimal:	27 91 Pn 32 77
	Hex:	1B 5B Pn 20 43
	BASIC:	CHR$(27);”[“;Pn;” C”;

		NOTE
	Pn is a decimal value that species the height of the font in
	units determined by the Select Size Unit (SUU) sequence. The
	width of the font is implicitly defined by the height. The
	default value for Pn is 100. The GSS sequence remains in effect
	until the printer receives another GSS sequence or a Graphic
	Size Modification (GSM) sequence.
S7C1T	Select 7-Bit C1 Transmission: This sequence causes the printer to
	use 7-bit encoding for all C1 control characters transmitted. All C1
	characters are then represented as two-character ESC sequences.
	General Command Syntax
	ESC SP F
	Decimal:	27 32 70
	Hex:	1B 20 46
	BASIC:	CHR$(27);” F”;
