PK80 Series 80-Column Printer User's Manual
This control code sequence enables 9-pin graphics. The variable m defines
the density of the print where 0 equals single density and 1 equals double
density. Since this is 9-pin graphics, two data bytes must represent each
dot column to print. The total number of dot columns to print is repre-
sented by n1 and n2, which indicates the length of the graphic string di-
vided by 2 that immediately follows. The length of the graphic string di-
vided by 2 must equal n1 + ( n2 * 256). Graphic string data that exceeds
the length of the print line is discarded. The maximum number of col-
umns to print in this mode is 480 for single-density graphics and 960 for
double-density graphics. Ensure adjacent dots in a given dot row are not
printed in double-density graphics design.

This control code sequence enables the graphic mode represented by the
variable m as shown in the table below. The total number of dot columns
to print is represented by n1 and n2, which indicates the length of the
graphic string that immediately follows. The length of the graphic string
must be equal n1 + ( n2 * 256 ). Graphic string data that exceeds the
length of the print line is discarded.

Draft mode is single pass, bi-directional, and prints at the highest speed
because it never prints adjacent half dots.
Half dot modes must go slower.
Unidirectional modes can be fast or slow depending on dot adjacency.
High quality print modes are slower because they print adjacent dots.
Enhanced or double-strike modes require multiple passes.
