(155, 235, n1, n2)D

This code selects high density graphic mode. The maximum number of vertical dots

is 16 and the maximum of horizontal dots is 1632. The n1 and n2 are binary numbers

that display the graphic data number. Note that 16 vertical dots require 2 bytes of

data, but they are considered as a single data block.

The relationship between graphic data and the printed dots is shown below

33. (1B, 2A, 6D, n1, n2)H (27, 42, 109, n1, n2)D

This command prints dot graphics in a density determined by the value of m (see

table below). The values of n1 and n2 are determined as in the other graphics com-

mands (i.e. n1 + n2* 256 = the number of dot columns). This command must be

followed by the correct number of graphic data (1 byte per column for m = 0 to

6, 2 bytes per column for m = 7).

34. (1B, 59, n1, n2)H (27, 89, n1, n2)D

This code prints high-speed, double-density dot graphics at 120 dots per inch. The

values of n1 and n2 define the number of bytes of data according to the formula

n1 + n2*256. Each byte of data controls the printhead pins in one vertical row of

dots. The maximum number of bytes of data is 1632.
