Technical Reference Guide – Command descriptions > 162
> Function:
Selects high speed double-density graphics (120 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
> 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)
High speed double-density graphics prints at 120 DPI. This
is the same density as low speed double-density graphics,
but the printer cannot place two adjacent dots in the same
row (quasi-density).
