Tally Genicom Matrix Printer manual Example for calculation of n1 and n2

The vertical resolution is 72 dpi.

The graphics image is printed vertically closed at a line feed of 80⁄720 inch. (Also see the sequences Spacing Increment (SPI), page 15, and Set Line Spacing (SLS), page 26. Example: CSI 80 ; SP G).

Example for calculation of n1 and n2:

The length of graphics is 80 bytes.

n2	=	number of bytes divided by 256
	= int (80⁄256)
	=	dec.0
	=	hex.00
n1	=	remainder of division of n2
	=	80 mod 256
	=	dec.80
	=	hex.50

Graphics data and text data can be mixed within one line.

Relationship between graphics data and needles:

Needle 1/3 ∙ 4/5 ∙ 6/8 ∙ 9/10 ∙ 11/13 ∙ 14/15 ∙ 16/18 ∙ 19/20 ∙
