Reassign Alternate Graphics Codes - Oki ML1120 Technical Reference Manual

Upon receipt of this code the printer switches to quadruple-
density graphics (240 DPI horizontal) for the number of
columns specified by n1 and n2.
> Range:
n1 = 0 – 255, Remainder of dot columns
n2 = 0 – 255, Number of groups of 255 dot columns.
n1 in conjunction with n2 specifies the total number of dot
columns to be printed in graphics. Dots = n1 + (n2*256)
Number of dots/line
Value
> Additional details:
The values for n1, n2 can be calculated as follows:
n = total number of dots to be printed.
n2 = INT (n/256)
n1 = n - (n2 × 256)
As quad-density graphics are printed in a quasi-density,
the printer does not print consecutive dots in any one row.

This command is equivalent to the 8 pin graphics mode
command specified by ESC* "3" n1 n2.
