You can use this command to reassign any of the 8-pin graphics modes to one of the graphics
commands (ESC K, ESC L, ESC Y, or ESC Z).
Parameter m
This parameter designates which of the four commands you're redefining. Substitute one of the
four letters (K, L, Y, or Z) for m in the command.
Parameter n
This parameter designates the density of the mode you are reassigning to the redefined code.
Substitute the appropriate value (0 through 7) for the density you wish to select, as taken from
the 8-Pin Graphics Density Codes table earlier in this chapter.
When you are ready to print a graphics pattern, send the redefined command, followed by the
graphics data.
For example, the following BASIC statement reassigns quadruple density to the command ESC
L:
LPRINT CHR$(27);”?”;”L”;CHR$(3)

This command permits use of all nine pins on the printhead. It operates exactly like the ESC *
command, except that dot columns are given two bytes each instead of one. The first byte for
each column represents the top eight pins, just like the ESC * command. The second byte is
128 if the bottom (9th) pin is to be fired, and zero if it's not to be fired.

Use this command to select the density and to define the speed and “word size.”
Parameter n
1
This parameter specifies the density. To calculate the value of n
1
, first select the dpi and density
you want, then determine the n
1
values for each from the table below. Add them together, then
add 96 to the total.
