Tally Genicom Matrix Printer - Manual (Page 302)

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 n
1
and n
2
:
The length of graphics is 80 bytes.
n
2
= number of bytes divided by 256
= int (
80 ⁄
256 )
= dec.0
= hex.00
n
1
= remainder of division of n
2
= 80 mod 256
= dec.80
= hex.50
Graphics data and text data can be mixed within one line.
